I have used The Struggle for Europe as a companion for Judt's Postwar, and I think it worked out well. Similar to Postwar, The Struggle for Europe talks about Europe's between 1945 and 2002. The difference between the the two is that this book feels more of a textbook, in the sense that it discusses only the outermost important events/ figures from this period of time in section (all having descriptive titles!) of roughly 25 pages, which is really nice if you just want to read/ refresh your memory about a particular topic. I was only superficial familiar to de Gaulle, Thatcher, Attlee before reading the book, and I enjoyed those chapters as least as much as I enjoyed the corresponding in Judt's book.
About one quarter of the book is about the Eastern bloc, with a special emphasis on USSR and GDR, but those sections are very good: in total they sum to a very good/ fast 100 pages overview of the Eastern bloc. Similar to Postwar, there is no big underlying theme/ motif in the book, but many "foxy" events whose presentations are pretty self contained. A main focus is on West and East Germany, starting with the separation at the beginning of the Cold War, the Berlin Wall, the change of politics from Adenauer's Westpolitik to Brandt's Ostpolitik, and Kohl's efforts for reunification.
Great effort, strongly recommended if you want to brush up your European history or if you want a fast, but not superficial introduction to post WW II Europe. It has a nice collection of pictures, too!
