It's not that simple. Iran is making a play for more middle eastern oil. Saddam did the same thing in the first gulf war with Russian arms. Russia is helping Iran do that again. If Iran controlled more middle eastern oil, Russia could literally bring Europe to its knees. Most of their imports are from Russia and Saudi Arabia. I think Russia has a plan for Europe and it includes the Iranians.

Of course there's no reason we should feel compelled to bail out Europe again either. Didn't really do much for us the first time. People in Europe should be alarmed at what is transpiring in the middle east. They're the ones that need to do something about it, not the US.
