First, you're calling the invasion of Iraq, the bombing of Iran, and all the other things the US has been doing around the world since as far as can be remembered "defense". Murdering villagers in remote Vietnamese villages etc. Secondly, military spending is more than 3.5% GDP. It is only 3.5% if you exclude pension and health benefits due to retired military, interest on past military spending (past as in, last year's) and so on. The real military budget is always underreported to a large extent.
