What politicians say publically versus what they actually agree to are two totally different things. It's simply vogue to complain about American led international conflicts right now. It's just a big show to drum up votes. One has to look no further than the recent press surrounding the nsa, echelon and other programs to see just how complicit other western countries are with American imperialism. Heck, even if they didn't want the US involved in the middle east, no one else is going to stand up to China or Russia if the US was to leave. So, everyone maintains status quo.
