OK then pick up your gun and go -- volunteer!
And if you come back in a box? WTF did you die for? Will the Iraqis and Syrians acknowledge your heroism -- fuck no. That is WW2 thinking. Do the Vietnamese build shrines to all the US servicemen that died in the Vietnam War? Fuck no -- many spit on the US and allied deads' graves to this day. Don't feed me that horseshit.
If the world was smart we would embargo weapons to the whole ME. They will run out of bullets and stop killing (so fast). Let them fight with what they can produce on their own.
Trump can hire Mexicans and Chinamen on the cheap and build a fucking wall around ISIS.
That is if you have the balls to do it -- given a chance -- ISIS would evaporate us. Harry S. Truman's dilemma in a modern-day context.
