Another poster mentioned artillery. The truth of the matter is the North Koreans have some 12,000-14,000 tubes (that's right, those numbers have three zeros) of artillery fixed in on South Korean and American positions. Some American outposts have 10 battalions worth of artillery targetted on them.
We're going to need to re-institute the draft, and big time. The Army barely has 8 combat divisions, and the Marine Corps 3. Anybody here who thinks we have enough forces to handle Iraq and North Korea both frankly don't know what the hell they are talking about.
