Time to send more troops to Iraq. I don't see any way that the United States is staying out of this one.
fyi..
If we become directly engaged with Iran, our forces in SK had better be put at a higher level of alert. I'm not sure Kim Jong Il will be able to resist a blitzkrieg otherwise. If we can't relieve SK under pressure, he can stay completely conventional and hold Seoul and Tokyo as nuclear hostages if we threaten nukes.
