Let's speak truth. We aren't going to take over 500 billion out of Defense, we are going to take it out of projected increases to Defense. Defense is so big it should be easy, but the Pentagon has to set priorities to buy expensive new systems it wants. Leaving Korea or Japan would be stupid. There are bases in the US we don't need and their are armies of civilians and enlisted men doing civilian jobs the Pentagon we don't need who, like other government agencies write reports and plan and meet and carry papers. Most of it is of little value.
