Kosovo (couldn't succeed without U.S. $$$s and blood) Iraq (sanctions fail...stick head in sand) North Korea (appeasement failure episode 2, now let's make it a US problem) Iran (Russia mettling, UN gets a big bark, but no bite) Syria (let's blame Israel and stick heads in sand) Sudan (what problem?)
