Secondly, allowing Iran to get nukes isn't a rational option. It would necessarily start a nuclear arms race throughout the entire region by nations wanting to gain strategic parity with their aggressive shia neighbor. Needless to say, a Middle East loaded with nuclear arsenals isn't in the best interest of the U.S. and the rest of the civi.ized world. ...to understate the matter.
competely = completed
“the operation would be competely quickly”
That ain’t gonna happen. If you really want to stop their nuke program, you’ve got to take out all of their several hundred installations. Even if we put boots on the ground, it would probably be another year before we could say with confidence that we had found them all.
You might be able to delay their program for a few years using a quick strike, but that’s not a solution.
