On January 19, Charles Krauthammer delivered a Margaret Thatcher Freedom Lecture at the Heritage Foundation. You can read the whole speech here. Food for thought:
The international community lies at the center of the Obama foreign policy. Unfortunately, it is a fiction. There is no such thing. Different countries have different histories, geographies, necessities, and interests. There's no natural, inherent, or enduring international community. What community of interest is there between, say, the United States, Iran, Zimbabwe, and Burma?
The international community is a Hobbesian state of nature with no universally recognized norms. Anarchy is kept in check not by some bureaucracy on the East River, not by some inchoate expression of world opinion, not by parchment promises adorned with disingenuous signatures, but by the will and the power of the Great Powers and, most important in our time, the one remaining superpower: namely, the United States.
The address builds on themes Krauthammer enunciated in his lecture "Decline is a Choice." Read the whole thing, as they say. You won't regret it.
