If the decision is going to be primarily made as a result of monetary factors .. and these (for now) are the most important to you, then go. Great opportunity for you to get way ahead, quickly. As far as personal security goes I don't think you have much to worry about unless the position you're looking at puts you in the streets of an Iraqi city. And I mean, literally, the streets.
My personal opinion is that the same people paying you all of this money are the same ones hoodwinking our government, causing the majority of our tax money to be funnelled into a war which has no concrete purpose or cause which could possibly benefit us and generally sinking the US into a governmental abyss along the lines of every other 'empire' that has come crashing down. Empiricism at its finest, even though most Americans would never admit it.
My father has the opporunity to jump overseas to do the same thing for a year. He and my mother desperately could use the monetary quick-fix but I've tried to encourage him to think about it from my previous viewpoint. Not sure it's sinking in - he's an old codger.
In either case, good luck to you.
