I don't see how sunnis and shiites shooting each other is going to make the streets of NYC any less safe. If anything, the men we bring home can hold up rifles at airports or work as sky marshalls.
And if some group does move in and set up shop with nefarious purposes, the nearby US bases (ya know, for the oil we're managing) will prompty cook the SOBs.
Try communating that to them and they'll fight back with the same flawed arguements that have been proven to not only be faulty, but also dangerous in the long-run health of the US. Trillions spent on a war that's going nowhere can't be a good thing, and neither can creating more world wide contempt towards America. Arond the 90's, the US was probably the most beloved country in the world, people spoke very highly of this country and Clinton. People around the world have now shifted their opinions and I can't say I blame them.
