Libya was overthrown, Egypt was overthrown, and we've been making attempts in Syria and Ukraine. And after failing to gin up support against chemical weapons, we're now bombing Syria because of some crazy rebels that are allied with groups we support.
In the bigger picture, we are waging a crypto-war with between Russia over energy resources from Russia and the Gulf into Europe. Pope Francis recently had the courage to call it as such:

So - to see Obama's peace prize as anything other than a partisan political joke (as you say, a "middle finger" to Bush) is a mistake.
Obama's administration has put the world as close to a hot-war between nuclear powers as we've seen in some time. It should make us angry - he was elected to stop the madness, and it seems like he is running business-as-usual.
