No, more people die. As evidenced by 9/11. The Iranians were so terrified of President Reagan that they let the hostages go the day he took office. They knew what was coming if they didn't behave.
Quadaffi and his flippin "Line of Death."

Preesident Reagan not only said, "Screw you and your 'Line of Death'", he went over the line and bombed the guy's flippin house. Didn't actually kill him, but got one or more of his kids...and that was that. Quadaffi has behaved himself ever since. On 9/11 he was the first to come out and say, "Not me! I'm not involved! My country supports America."
When they know that screwing with us means they will die, they don't take hostages or come and kill us. Therefore, we don't have to kill them. And NOBODY dies.
When you get weaklings like Presidents Clinton and Bush, you get war.
What do you want to wait for? Mushroom clouds?
