Please cite credible proof of this. Politifact looked into this and the conclusion was that the Obama administration has killed more of the higher up terrorists. Obama also has had more time to kill terrorists (entire 2 terms) while Bush was asleep as far as terrorism is concerned before 9/11. Obama has better technology than Bush had.

Regardless, that means little. The current extremist situation that breeds terrorism has its roots from a multitude of causes, most of them prior to Obama's 1st election to the white house. It isn't a simple problem with a simple solution even if there are a lot of simpletons that think so.
