The knee jerk Conservative reaction is that the defense budget can not be cut at all. It is absurd to say that there is not one tuba player in one band on one base that cannot be done without. And in a budget this big there has to be room for improvement without reducing defensive capability or making any of our brave soldiers do without supplies, support pay or medical care.
Here's a start: When Clinton was "nation building" Conservatives and Republicans were properly strong in opposition to it. The same thing is going on in Iraq and Afganistan and now it's OK? It's time to go. Give each of them an assault rifle (if they don't already have one) and leave. If the mission can't be sensibly defined - and it can't - it's a lousy mission.
