David Halberstam produces here a useful historical document, as an experienced journalist who undertook many primary source interviews to get some sense of the conflicts between the military and the political leadership over policy and power that took place under Bush I and Clinton (I).
The narrative is dominated by the crisis in Yugoslavia. This helped to define the new liberal internationalism that emerged in subsequent years (although Halberstam was not to know this). The book might be seen an ur-source for evaluating the seeds of the mess we are now in.
Completed just before 9/11, the book is remarkable for not mentioning the Middle East, bar one passing reference to the Peace Process, and relations with Russia are only considered indirectly. Fortunately, the collapse of the Soviet Union was not a matter for the generals as imminent war.
This all gives a slightly skewed picture but only if we do not understand what Halberstam is doing here. He is not writing a history of foreign policy or of national defence but only one about a dialectic - that between military realism and political short-termism and ideology.
Evaluating the lessons of this book might result in a very long and detailed essay so I will only pull out some themes and let the reader explore them himself based on the facts that Halberstam lays out in his book. You can judge whether his (and my) interpretations are correct on those facts.
I rather trust Halberstam within the limited territory he is exploring. He usefully understands the historic pull of past wars on American politics and on military thinking and he is an 'insider' insofar as an intellectual journalist can be one in a relatively free society.
The first theme is the importance of a President who actually understands the world he is dealing with. George H. Bush comes across as sophisticated, surrounded by people of judgement and experience. Clinton horrifies somewhat as clever and shallow, vacillating, almost 'feminine'.
Nor is Clinton's team particularly impressive. I do not think that Halberstam is showing any partisan bias (unusually for American political writing). They really are unable to cohere around clear macro-analyses and decisive effective planning with some notion of consequences.
I refuse to draw easy conclusions about the competence of Hillary Clinton who may soon be leader of the largest military empire the world has ever seen. She now has significant experience and she is not her husband but the historic conduct of Democrat foreign policy might reasonably worry us.
The second theme is the conservatism of the military. One leading figure is quoted as saying that the Democrats want a small military and to use it everywhere and the Republicans a large army and never use it all. This is borne out by the book (though things change with Bush II's neo-cons).
Surprisingly, one comes to the conclusion that, all things being equal, the US military and the Republicans to whom they tend are America's Peace Party and the Democrats, in opposition to traditional European 'Leftism', are the War Party.
Self-evidently, the American military were still in super-war mode, against the threat of a major world war, and adjusted only slowly to the collapse of the Soviet military threat. They also had no illusions about the massive costs of ground war operations (and remain cautious today).
The Gulf War under Bush certainly restored the American military's sense of what was possible against a second rank traditional state power but it told the military nothing about the costs of mountainous guerrilla war or managing failed states
Former Yugoslavia and Somalia taught them what the later Iraq War was to teach them. Destroying a formal state power is one thing and, if you are prepared to accept the body count, possible but reconstruction and policing are another thing. George C. Marshall was very much an army man.
To win is not to hold or settle. Body bags where the public cannot see their essential interest in the game (after all, America needed Pearl Harbour to undertake its mission against the rise of national socialism) implied a repetition of Vietnam's undermining of trust in the system.
Could liberal internationalism have gone ape around the world if 9/11 had not happened? We doubt it. And the strike against Iraq (unconnected to 9/11) mirrors the decision to go for Germany first instead of Japan after 1941 because of decisions already made elsewhere.
What strikes one here is that, until George W. Bush decided to invade a country on spurious grounds, the military and political establishment were both consistently nervous of taking any armed actions but for different reasons. How that changed is the story of the last third of the book.
For the military it was the justifiable fear of the costs of failure and concern at the inability of the civilians to come up with any plan for consequences (which was to prove fatal in Iraq). For civilians it was fear of domestic electoral consequences and simple ignorance of strategy.
What triggered interventionist strategies was ideological sentiment - mostly Democrat excitability about humanitarian issues in countries they scarcely understood. They certainly had no serious plan about what to do if the aggressor was beaten. It was "Something must be done!"
The blundering around in Clinton's first term is embarrassing - whether it be Somalia, Haiti or Bosnia. The sensible Vance-Owen proposals were sidelined by political half wits only to be returned to in essence and in a weaker version after much misery later.
Allies play scarcely any rule in the deliberations except as dead weights on action (early Clinton) or agents provocateurs (later Clinton). Speaking as a Brit, the US has often been manipulable by foreign powers from the British Empire through to Israel. This period was no exception.
By the second term we are moving into legacy time, that point where a narcissistic President starts to think about how he will be seen by history and realises that he is going to be seen as a middle ranker unless he solves some big question.
The Middle East Peace Process was the obvious solution but that all falls apart on the stunning obduracy of Yasser Arafat so the crisis in Yugoslavia emerges as the constant sore that is high risk but also high reward if something can be done - yet it is not the President who really drives this.
Where Halberstam is particularly good is on the personal dynamics that are the essence of the American State at the highest level - who is up, who is down, who is respected and who is not, what personal histories dictated what ideological presupposition.
We see the emergence or rather convergence of activist liberal internationalists genuinely concerned about the condition of the peoples of former Yugoslavia but also activists for the use of US power to order the world (a theme to be taken up by the neo-cons with more aggression later).
There are State Department officials and policy wonks but these are buttressed by two new forces - Wesley Clark as SACEUR and the arrival in London of the 'hawk' Tony Blair who seems to have had a ready-made model of global military intervention to hand.
The story of Wes Clark is most instructive for two reasons. He was clearly hated by the US military establishment but his role as SACEUR allowed him to push the envelope in using military resources to pursue a war that they saw no reason for. The second reason was air power.
The eternal conflict within the US military over the value and role of air power was not quite resolved by the Gulf War but it was arguable now that a state could be brought low simply with aggressive targeting by a new stock of precision-guided weaponry.
The radicals wanted to show that air power alone was sufficient to bring a tyrant to heel. Wes Clark (an army man) drove this tactic as far as he could against Milosevic despite European doubts and divisions in NATO and Pentagon attempts to deny him any ground support resources.
In fact, it worked but not in the simple way that liberal intellectuals have presented to the world since. It worked because the US was actually backing gangsters as bad as Milosevic in the KLA (just as it had earlier backed the quasi-fascists of Tudjman's Croatia) and the Serb people revolted.
As Halberstam points out, the Serb internal revolt was enabled because Yugoslavia precisely was not the total dictatorship of myth - Former Yugoslavia was a hybrid of single party secret police control and relative intellectual and civil society freedom. Milosevic pushed the people too far.
At the same time, Serbia lost its negotiating position because Russia, economically-dependent on the West under the corrupt Yeltsin, simply and overtly withdrew support from its old ally. This was from weakness and another seed of the future - Putin would reverse this within a few years.
Air power 'worked' but it could not be said to have done so without cost. The US was never tested with a ground invasion (the US military clearly did everything it could not to allow SACEUR that option) and the humanitarian mission was actually as much in support of gangsters as victims.
What Halberstam does not write about is the medium term and long term consequences of the flaccidity of a Clinton looking for a legacy, whose wife clearly has inherited that legacy not as short term fix but as an ideology - which may makes her as dangerous as her rival, more so perhaps.
The discovery of air power under conditions where the old superpower Russia could be treated with contempt and China was still rising but without skin in the game - and monomaniacs like Tony Blair could offer unstinting support - created a new mentality of 'possibility'.
It was not the humanitarian Democrats who took things to the next stage (although Al Gore is likely to have been a strong interventionist) but Bush II with a determined model of using humanitarian rhetoric to take out states that challenged US authority to set the global agenda.
Well, we know how that turned out - but equally interesting is the trajectory of non-US liberal internationalists into an ideology that abandoned over a century of Leftist aversion to the use of war and the effect of the Yugoslav warlets on a revived and aggressive NATO.
The first created Left claques for criminal operations against Iraq but also for an acceptance that military forces could legitimately be used to enforce Western liberal standards. Blair led the US by the nose after the apparently successful Sierra Leone campaign and then was led by the nose.
The second used the humanitarian model as cover for the expansion of liberal values by what had been hitherto an essentially defensive alliance, turning it into a force for potential aggression against anything that might prove a threat in the future - Russia being the most obvious.
The realist 'sphere of influence' understanding that reached its high point at Yalta gave priority to global peace over human rights. The collapse of the Soviet Union allowed liberals to switch the emphasis from global peace and the nation state to human rights (inherent in the Atlantic Charter).
Despite the Cold War, the superpowers maintained a sort of balance in which spheres of influence and ideas were contested short of direct military conflict until one of them collapsed. At that point, the beaten power could have been respected or treated as defeated - the West chose the latter.
Such triumphalism might have worked if the world carried on along the same trajectory but Russia revived with reason to be distrustful and not grateful, China watched how the US behaved and learned lessons and Political Islam and failed states started to grind down the American Empire.
Rights sound noble especially to intellectual leader writers in the West, easily seduced by ideas, but it meant that NATO started to move into every political vacuum presented to it, backed up by trade promises that could not be safely fulfilled, especially in relation to free movement of labour.
It then participated in the slow degradation of the European West's borderlands by interventions that pushed it right up to the borders of Russia itself and destabilised regimes such as Libya's that were brutal but which also acted as defensive lines against migration, terror and organised crime.
None of this could be known by the actors in Halberstam's book, completed in 2001 as contemporary history, but the crisis of our time cannot just be put down to the exploitation of new powers by George W. Bush and the Cheney Gang - that is all too easy.
It comes ultimately down to the narcissism and foreign policy ignorance of his predecessor whose weakness included an inability to engage with his foreign policy staffs and listen with care and respect to his military - and to allow men like Blair and Clark to drive the agenda.
The competent one, George H. Bush, turned out to be the one who could not win an election because, understandably, the American people are and should be most concerned with domestic prosperity and the theatre that is American politics. Democracy is problematic for empire.
We are coming up to another decisive election in a few months and there is an unusual intensity in this one regarding foreign policy. The foreign policy estasblishment that has locked itself into power since Kosovo is clearly terrified of a Trump who asks too many difficult questions.
The question is whether Hillary is better than her husband - that is a question for Americans to answer but insofar as her time at State was a continuation of the last days of her husband's rule under a more moderate, apparently competent and sensible Democrat President, doubts are normal.
As for Halberstam's book, it remains worth reading even if he could have done with a bit of sub-editing at times in the first third where he repeats himself a bit. His analyses are always plausible. His insight into the micro-politics of American statecraft genuinely enlightening.
It is worth reading the very short post-9/11 introduction after rather than before the rest of the book. Its tone is at variance with the main text and it reminds us that Americans really were shocked into counter-aggression by the Islamist aggression - and confused by what had happened.
But, finally, what really strikes me about his text is that it is part of a non-reflexive culture that finds it very difficult to ask more fundamental questions about its own imperial conduct - what does the nation actually want and do its people have much informed say in that decision?
