Yes, the US bombed Yugoslavia (Serbia, to be precise), but wasn't that after Europe stood by silently and watched as thousands of Bosnian men were killed in concentration camps (Srebrenica massacre)... yes, the same style of concentration camp that people swore would never happen again, especially after the atrocities in World War II?

Let's try to put US actions into perspective once in a while, instead of simply praising US folks like Obama for inaction, for example, inaction on Syria, Iraq and ISIS that has led to the largest refugee and humanitarian crisis since WWII (especially since it was Obama who warned Syria on the use of chemical weapons, and then stood by and did nothing to back up his statements).
