Killing Arabs will put hair on your chest, son! Not only is it the best feeling in the world, it is more awesome than the pump! Best of all, you don’t even have to join the military to do it! Just go find an Arab and shoot him.
You say that’s murder? No way dude! You can just use the same defense as our great leader did - the guy may have had the same weapon you sold him a few years ago and may or may not of had the intention to use it, even though it was rusted out by now and they no longer made bullets for that type of gun anymore. It was pre-emptive self defense, not murder. It’s failsafe, bro!
