“Patriotism means to stand by the country. It does not mean to stand by the president or any other public official, save exactly to the degree in which he himself stands by the country. It is patriotic to support him insofar as he efficiently serves the country. It is unpatriotic not to oppose him to the exact extent that by inefficiency or otherwise he fails in his duty to stand by the country. In either event, it is unpatriotic not to tell the truth, whether about the president or anyone else.”
― Theodore Roosevelt

“Patriotism is supporting your country all the time and your government when it deserves it.”
― Mark Twain

“Never think that war, no matter how necessary, nor how justified, is not a crime.”
― Ernest Hemingway, Ernest Hemingway: A Literary Reference

“In every age it has been the tyrant, the oppressor and the exploiter who has wrapped himself in the cloak of patriotism, or religion, or both to deceive and overawe the People.”
― Eugene Victor Debs
