In the last few days, Obama administration officials have frequently faced the question: Is the fighting in Libya a war?  From military officers to White House spokesmen up to the president himself, the answer is no.  But that leaves the question: What is it?

In a briefing on board Air Force One Wednesday, deputy national security adviser Ben Rhodes took a crack at an answer.  "I think what we are doing is enforcing a resolution that has a very clear set of goals, which is protecting the Libyan people, averting a humanitarian crisis, and setting up a no-fly zone," Rhodes said.  "Obviously that involves kinetic military action, particularly on the front end."
