|Congress controls the spending. Btw, "Bush's wars" propaganda is getting boring. Democrats overwhelmingly supported them (unanimously in case of Afghanistan) and it was Clinton admin that set the stage for Iraq war with regime change policy (Iraq Liberation Act 1998). You can argue whether it was right or wrong but you can't blame just one side for it - they all had the same intelligence. Same applies with the current administration. Would they really cut the spending if Republicans weren't fighting for it all along.
