The quality of the answers to this question so far, except one is really disturbing.  First of all, the U.S. is not in a war with Iraq.  The Iraqi Government is working with the United States to put down an insurgency which challenges the legitimate elected authority of the Iraqi Government.\n\nAlso, Russia does not pose a great threat to the US from a conventional point of view, although they still have nuclear weapons.  Relations between the US and Russia are not bad at all, although there are bumps from time to time.  YOu should be more worried about the Iranian or North Korean situation at this point.  Between those two, North Korea has a much more impressive, although logistically hollow military.  Iran is not considered to be an offensive threat, but could and would defend itself fairly well against invasion.
