In America, a warlike politician is called a hawk.
To me, it looks more like America has a war phallus that needs to ejaculate regularly so Pentagon won't get blue balls.
I don't think most presidents entering office enjoy giving an order to kill people. I *do* think the generals from Pentagon *really* pressure them into doing so anyway, though.
Imagine being surrounded by the top generals at Pentagon and they're all telling you to strike Iran. Do you have the strength to resist?
