A less charitable and more likely explanation is that Obama is treating the war in Libya as he treats all sorts of other things, as actions designed above all to serve his own political interests and ideological visions. Whether it does even that depends on what the situation is like in Libya when the 2012 elections roll around.
As for the national interests of the United States of America, Barack Obama has never shown any great concern about that.
President Obama started alienating our staunchest allies, Britain and Israel, from his earliest days in office, while cozying up to our adversaries such as Russia and China, not to mention the Palestinians, who cheered when they saw on television the collapse of the World Trade Center on 9/11.
Many people in various parts of the political spectrum are expressing a sense of disappointment with Obama. But I have not felt the least bit disappointed.
Once in office, President Obama has done exactly what his whole history would lead you to expect him to do-- such as cutting the military budget and vastly expanding the welfare state.
He has by-passed the Constitution by appointing power-wielding "czars" who don't have to be confirmed by the Senate like Cabinet members, and now he has by-passed Congress by taking military actions based on authorization by the United Nations and the Arab League.
Those who expected his election to mark a new "post-racial" era may be the most disappointed. He has appointed people with a track record of race resentment promotion and bias, like Attorney General Eric Holder and Supreme Court Justice Sonia Sotomayor.
Disappointing? No. Disgusting? Yes. The only disappointment is with voters who voted their hopes and ignored his realities.
