How much does the National Security budget of the US amounts to?

I can't know (you have to pay to get access). I wish I did though. I have always been wandering what a drag the "Defense" expenses are on countries. How better will we be if we didn't have to spend all those money and energies in unproductive things? Of course we may niot be that better as our neighbours would invade us to rob our richs...

It is a sad, sad world...
