First off..they do have nukes..the North has tested them underground...Studies from the US / Japan... says it had the force of maybe 2/3 times that of "big boy" used in WWII on Japan..And they have out right said they have them ready to use...And like us...if we thought we'd be taken over by another country by force...we'd use them!! Well...so would they. Experts (our intellegence community) say they have maybe 8 to 12...last year...next year...15/25...the next year..35/50 ready to use; and maybe a dozen..for small battle field use..and torpedos war heads! Im other words...we would be fighting a foe that will be a "stand and fight" war, for a change..And also...they do have the means to deliver these nukes...about as far as Peal Harbor, accurately...at this time. Also....I've been talking to some "so called experts" on the matter; a few that have been stationed in the south......they said the South wouldn't stand a snowball chance in hell.. at holding back the North's army...as a matter of fact..the play book on this battle...does look quite bleek. They say the North if they wanted to;...could take over about half of South Korea...before any kind of "offensive" messures could come to muster...with much of it being American forces might and will power ....could push them back, maybe. The lose of life...and damage would be such a toll...that it is about unthinkable. So any thoughts that the South could hold back the largest ground force to ever march on a battle field...is a pipe dream.
