You are absolutely right about the Germans arming the murderers in the Balkans, !mitation.
But there's more to that story: in 1992, the war was about to be settled when Bosnian-Muslims, Bosnian-Croats and Bosnian-Serbs signed the Lisbon agreements, backed by the EU. The three leaders of those fractions agreed to have three independent regions, each with their own government.

A couple of days after the agreement was signed (and after only a couple of days of peace), the American ambassador Zimmerman stepped in and convinced the Bosnian-Muslim leader to withdraw from the agreement. The Bosnian-Muslim leader agreed (with the promise that the US would recognize Bosnia - Muslim-Bosnia, that is - as an independent state), and what followed is one of the bloodiest wars in modern history (over 500,000 people died). The US was arming the Muslim-Bosnians, and so were a bunch of Western European countries (Germany, most of all)... After the war was over, the land given to the Muslim-Bosnians was waaaay less than they would have gotten in the Lisbon agreements... suckers.

I admitted that the Germans armed the Muslim-Bosnians... now all you've left to do is that the US did the same (and yes, it was Clinton who authorized it)
