I don't think we should police anything, or go anywhere that is a not a direct threat to us. We have the means and tech. to turn any country to dust that points anything at us, no sense in having to go there. First thing we have to do is close our borders and clean ourselves out from all illegals no matter how long it takes to ship them all out, once you get that done secure all borders, there is a proper way to enter and a proper way to stay here.
We deserve our sovereignty, we should demand it, as Americans. That word should mean something.
You can't save the world, you can't make other people be like you want them to be, they must get there by themselves somehow. If they are really a threat, turn them to dust and get it done with. If you don't have the guts for that, let it go. That attitdue in itself would go a long way to anyone wanting to mess with us. You don't slap something that hits back 5 times harder
