World War 3?  

Well Let's see. The answer to that is NOTHING. Obama will give a strongly worded message to North Korea. That's it.

It's not what he should do mind you, but it's all.

Kinda makes you will Ronnie Reagan was still president huh?

Gee Laglen-way2go with bringin' me all down with reality and stuff right before my coffee run. I'm already down with the oil spill in ma backyard. And I aint talkin' Beverly Hillbillies neither. Gosh Darn-it! I just got done watching the movie,"Class of Nuke-em High." http://www.youtube.com/watch?v=3F_zWIs0S9k

i really dont know why we even bother with these little pests, they all talk a big game but when push comes to shove and we are in dire straights if barack baby doesnt do something i think our military is gonna push barack aside and take care of business, no questions asked. sanctions my ash enough talk, send in some mercs and take that little nut job in the north out.

I think if it had been confirmed immediately after the attack South Korea would have responded with a counter strike. I don't think anything is going to happen now though. I'm with mike....a strongly worded reprimand and some begging the UN security council to impose more useless sanctions and hemming and hawing.
North Korea is pretty well contained anyway. Despite one of the largest militaries on earth...it is not very technically advanced, the don't have an effective delivery system for their nuclear weapons and all the power is centralized and confined to Kim Jong Il and some top military leaders, we can take those guys out any time we want really.

I would hope that the U.S. stays out of it. Let North and South Korea deal with their own problem. We have enough on our plates already.

Personally I think North Korea won't be a cause of the WW III.
China, the only big commy country in the world, after its emergence, had never enjoyed anything fancy. It produced good things and sold it abroad, and consumed the bad ones. Typical chinese, I can say. (Btw, not to get anyone flaming me, I am one.) Today's China's economic growth was never thought of by anyone, and I don't think China will let a WW III take away what it's enjoying now.

The only thing Obama will do, I think, is to use what's known as diplomacy. There will never be a military action ( and I think Iran knew it, it was why its president had the nerve to laugh at Obama).
From the little I read on him, somehow I feel that this is not a man of action. Obama seems to be of the same kind with the president we have here. Diplomats, relying on words only. When Malaysian ships entered our waters, the president (ours) sent someone to talk to Malaysia, and didn't allow our ships to fire. They were told only to follow and monitor. So it was how it was done. Malaysian ships kept on entering our waters and our ships chased them only to watch them from afar, in the end. lol. I think they're the kind who will hit back physically only when they see a speeding bullet.

As for the economy, I don't think it's ok for the US to run another war at this time, as it will slow down the recovery. This is boring to hear, but really, our economy depends so much on US. I don't know how it could be like this, but whatever happened to the US, we're hit, too. It's both good and bad news for us. It's good as if the US wanted to make us an ally, the US would try to change us, and we finally would get more freedom. The bad news is, I don't see Obama's administration will do it.
Just some to explain how I see the connection of both nations, the US and Indonesia.

Money just keeps stacking up whether it's in war or peace, as well as debts... It's such a shame that human advances don't match with spiritual. I really just find it confusing why North Korea stays the way they are..what a shame that some people can't really enjoy peace and appreciate it..I believe it's time for us to think not for ourselves...
