Today, as Obama is being pushed toward another futile round of peacemaking in the Mideast, prodded to intervene in the ethnic-civil-sectarian war in Syria and goaded to draw a “red line” for war on Iran, he should ask himself: How would America’s vital interests be imperiled by staying out of this particular quarrel, conflict or war? Why are all of these crises somehow ours to resolve? What are the odds that we can resolve them? We are out of Iraq, and leaving Afghanistan by 2014. Should we go back in, or as Obama pledged, do our “nation-building” here at home?
