Bloody borders? What nation doesn't?
You guys are all out to lunch.
There must have been a lot more Muslims in Western Europe than I thought.
Really? Western Europe? How many wars have been fought in Western Europe in the last year? I can name a couple in the Middle East. I would wager that a majority of the wars/insurgencies going on right now have muslims involved on at least one side.
Who said anything about the last year?
Well, how far in history do you want to go?
Well, though some of these aren't wars, there were the Years of Lead in Italy just a couple decades ago, there were the troubles in Ireland, there was the Basque conflict, while not exactly Western Europe, there was the Greek Civil War in the '40's, there was the Spanish Civil War, there was the Irish Civil War, the Irish War of Independence, though - again - not exactly Western Europe, there was a war between Hungary and Romania around 1920, the world wars of course, the Austro-Prussian War, the various wars of Italian independence, the Hungarian revolution, and probably many things I've either forgotten or didn't know about.
Then if we include the United States, there was the invasion of Panama, Grenada, the Vietnam War (no Muslims involved to the best of my knowledge), the US invasion of the Dominican Republic, the Korean War of course, the Spanish-American War, and countless other conflicts.
Then there have also been many other wars not involving any Muslims at all, such as the First Indochina War, the civil war in Paraguay, the civil war in Costa Rica, the Laotian civil war, a civil war in Guatemala.
Then if we'd like to talk about how people in general, as opposed to just Muslims, do horrible things for power (which is the real cause of virtually any war where religion is used as a cover), we could mention the Holocaust, the mass murder committed by Stalin, the Cultural Revolution sponsored by Mao, the terrible, terrible things that the Japanese did to prisoners of war, the horrible persecutions of the British against the Irish, and against Catholics, etc., etc.
