Does anyone believe that the USA would ever defend Japan if attacked by North Korea?

Well it seems you don't know your *** from a hole in the ground. But we do have a treaty with SETA and Japan.

Bombing North Korea would be the end. God I hope not they kicked our butts the first time and will this time. Don't you all know weapons including nukes mean nothing if you have enough people? During Nam, the NVA overran base after base and all the weapons in our arsenal could not stop them. In October 1950, China entered the Korea war and kicked our butts. They DARED us to drop the atomic bombs on them. They knew their population was so large that for us to be able to put a dent in it would have caused so much atomic energy to have been expended the world as we knew it would have ceased to exist. Well, they have even more people now; we would have a hard time using nukes on North Korea, as due to their proximity to South Koreas we would be killing an ally. The North Koreas rolled over the South in 1950 but would have a harder time this time but would prevail. Japan has a non-aggression Constitution but I believe they would have to come to the aid of the South. If not and the North wins and eventually rolling over Japan. I don't think American could stop them this time, too much political correctness plus big brother China. No, North Korea would not be someone anyone should wake up!

No, only kids, literates and that bunch of professional losers believe that garbage of aggression. Have you ever wondered why China is everyone friend and why everyone in a political situation listens to them and takes their advise?

Yes, we know it is morally right and we have to defend Japan, because they are one of the five permanent members of the UN. If we didn't defend Japan, then the world would look at us as traitors and cowards. Japan has helped us in Iraq with troops and has given us very good support ever since WWII. If we didn't defend Japan, North Korea could potentially take Japan over or kill many people if they decide to launch nuclear weapons. Standing aside, not taking any action would make things very bad. After Japan, they could decide to attack the US, because we are the next closest country in their range (if they get missles that can go far enough), or our interests, so by defending Japan, we would be defending ourselves and our allies. We could slow them down if they decided to attack Japan and we helped defend Japan. Japan would come to our side if we were attacked.

The U.S. will, without a second thought, defend one of it's largest trade partners. Your question actually makes no sense. "Ran us out of the Philippines"? They didn't run us out, we were defeated in battle. A few years later we "ran" the Japanese out of the Pacific Islands? No, they were defeated in battle. The meat of the question is will we "defend" Japan. The Japanese need no help with the likes of Korea. There are no samuri in public any longer, but never underestimate the courage of the Japanese. They were ready to meet invading U.S. troops on the beaches with spears! Yes, spears of sharpened bamboo. Actually, I think we could use some Japanese help in the sandbox! Some of the fearless fellows (Think Kamikaze.) in the black undies! Im talking Ninga, of course. But they were (Are?) some bad dudes. You can't beat the Japanese for putting honor before self, except possibly in the U.S. Marine Corps. (I was just an Army puke. Our motto was when you hear the gun, then run. Notice I did not say if it was away from the fire, or towards!) I won't champion MacArthur. He did a good job of building morale when the stuff hit the fan, but he had this "I" complex. Everything revolved around him. You can't get away with that now since commo is better. But then again, that may be why nobody can name a commanding U.S. general! Stick a fork in me, I'm done with this question.

An attack on Japan is an attack on the US! You can take that to the bank. The US commitment to Japan is ironclad, except the US is to the point that it will not discourage Japan from developing it's own defense mechanisms. For now, and probably for ever more, Japan's non-aggression pact will become nil and void.

I heard someone say recently, that all Japan needs is one long weekend to get up to speed on it's own nuclear program Don't forget, Japan owns more plutonium than any country on earth.

Let's just hope that we aren't creating our own monster, if Japan becomes another super power. Once it starts down that road, I'm sure that 'super power' will be it's objective.

The U.S. would defend Japan if it were attacked by North Korea.

Japan is an ally. It is also a trading partner. World War II is over.

Why wouldn't they? America is such a coward. If NKorea attack japan, i think USA will fire its nuclear missiles from its submarines in pacific to Japan indiscriminately, and say its aim is North Korean invading forces

They do not care on civilian casualties, like what they are doing in Iraq

There is no doubt we would defend Japan. There is a treaty to protect Japan and Japan (in turn) keeps its military purely defensive. This is written into Japan's post war constitution. There are far too many strategic consequences of not defending Japan.

I can't disagree more on your historical point about "General Mac". We could not afford to have a general with his knowledge of doctrine and military operations fall into enemy hands. The decision to leave was sound militarily, and allowed the US to make headway later. There are plenty of sound reasons to dispute General Mac's greatness in history, but withdrawing during that conflict isn't one of them in my opinion.

Yes we would and The USA retreated from the phillipines because they were fighting a losing battle at the time. Also the phillipines belonged to the USA at that time actually. Also the USA did come back to liberate the Phillipines.

The danger isn't North Korea, it's China who probably has a mutual defense treaty with Korea like we do with Japan.

That's why I don't think it will come to that.

What will probably happen is Kim Jung mentally ill will sell his nukes for a kings ransom to oil rich arab terrorists and one will be dropped on Jerusalem.

Then it's "all bets off" in terms of the kind of war that will ensue.

What's big and sandy and glows in the dark?

The rest of the middle east if Israel is ever nuked.

I think the US would defend anyone and everyone if it benifits the politicians. The one to worry about is China.
