they really invaded iraq because they assumed there's really wmd there and they admitted it that they are wrong.
the world will always have wmd whether we want it or not. that's reality. for now.
good news is the world is trying to eliminate these weapons. it's not on the headlines or in the news most of the time but it is happening.
could north korea deliver its nuke to south korea or japan? i doubt it. having a nuke is different from getting the nuke to your 'enemy.' will they do it if they are capable? without a doubt, no. seoul is too near the dmz. and they will not use it on their korean brothers. this two nations, the us, and red china are the lifeline of north korea. they are the one feeding them, literally. the problem with north korean leaders that they are stucked in a 'cold war mentality.' they think they could blackmail the world in acceding on what they want. the world most especially japan is uneasy but i feel that this crisis on north korea will be settled peacefully.
