Because President Obama is weak in his foreign policy, ISIS/ISIL terrorists remain strong and have continued murdering mass numbers of civilians. The attacks in Paris are the latest in a long line of terrorist acts committed by that group. The element enabling their continued attacks is Obama’s exclusive reliance on air power, which, by itself, is an ineffective strategy. In the past, Obama has said that he wants to avoid fighting a ground war with the terrorists and wants to “work with” our allies. As a result, ISIS continues growing stronger, since you can not defeat an aggressive enemy solely through air power. Air power was meant to reinforce ground assaults on the enemy. Obama’s use of air power alone has led US-allied nations to using their own, usually weaker, militaries to fight ISIS terrorists. In the case of Iraq, they lost.
They lost one of their recent battles due to having less training and fewer resources than more prosperous countries, like America. They also did not have the support of the US military. Nor has the US, under Obama’s direction, become “the leader” in such battles.
