The difference between then and now is Iraq is justified, Kosovo probably would have benefited from diplomacy.
We didn't have a cease fire with Kosovo that required the specific actions Iraq was bound to do at the end of the Gulf War. The two wars are far from the same threat to us and the Iraqi's had the added bonus of daily terror from Saddam.
Kerry says: to undermine our hard-fought peace or spill over into neighboring countries, precipitating the further destabilization of the region.
Kerry also says way back then: would send a signal to dictators from Baghdad to Pyongyang that it doesn't take much to put the United States and the world on the run.
You get the picture, Kerry wants it both ways and I was just pointing out another reason the man shouldn't even use the restroom at the White House.
