If you declare war on a stronger country they don't become hypocrites for ending the conflict.

Like all terrorists you try to rationalize the atrocities by making wholly inappropriate comparisons and going back to a point in history which aids your ridiculous argument. Any military activity carried out now in Afghanistan or the Middle East is in direct response to the continuing threat which the Muslim terrorists emanating from those regions of psychopathic lunatics represent to the civilians of the western nations. The United States never started any war in their entire history and any conflict in which they were involved was to support or establish a fair and democratic society. America has never aspired to establish an empire or dominate the peoples of any foreign country, but they did, and still do, try to protect their citizens by taking the war to the enemy. That's called good military strategy. The armies of the major European nations have been knocking seven bells out of each other for centuries but apart from Germany have not willfully targeted civilians. There simply is no comparison between terrorists and a legitimate national defensive army. Surely even a benighted fool like you can recognize what would happen if the raving madmen of the so called I.S, had the same military hardware at their disposal as the U.S.
