I personally don’t see anything wrong in wishing that "our" side wins – I hate it when airplanes fly into "our" skyscrapers, and people have to jump out the windows. It makes such a mess.

I might add drones and Hellfire missiles to the sticker.

Were one not so cynical (and you know where I stand), it could be said that by having an Imaginary Sky Deity (ISD) bless fighters, the blessing intended by most (but not all!) bumper-sticker wielders would be not that they prevail in battle, but that they come to no harm. (Being a sniper is very hazardous.) Of course, the greatest blessing for "our troops" would be that the conflict ends, which extends ISD’s blessing to both sides, and everyone gets to go home. I can agree with that one.

But you won’t find it on my car.
