"the only time there is a real threat of it is when there is a dictator who is actually not right in the head. "
Because it was an "insane dictator" that invaded Iraq for no reason, right? Oh wait, that's a 'police action', so that doesn't count. There is nothing more worn, trite, and tired that the propaganda of calling anybody who opposes America "insane".
" the world now does not believe in conquest. there is a UN resolution against it."
Yes, but that's a separate point from whether conquest "works". It clearly works, whether people find it normatively acceptable is a separate point. And just because outright conquest is not acceptable doesn't mean that there aren't serious disputes about territory, and that war couldn't erupt about entities that weren't considered legitimate like Taiwan, Palestine, S. Ossetia, etc. IN such cases, it wouldn't be considered "conquest", but the effect would be just the same. Surely if China liberated Taiwan nobody in Beijing would say they are "conquering" the island.
"we attacked back *because you can't conquer other states*"
Unless of course South Korea conquered North Korea, then we'd be all for that. Or, in the 1970s, we'd certainly support South Vietnam conquering North Vietnam.
"yes i know they had oil but it was also just the egregiousness of trying to actually conquer another state that made us step in. "
Well if people are interested, the US essentially told Kuwait not to cooperate with Iraq on slant-oil drilling, debt, and oil production levels. Numerous attempts at compromise were spurned by Kuwait, at America's behest. The invasion of Kuwait was a set up. I don't think anybody gave a damn about the sovereignty of some emirate run by the Sabah monarchy so much as they cared about keeping Iraq away from control of Middle East's oil supply. Which is why they made up crap about 100,000 Iraqi soldiers lining up along the Saudi border in order to get people to sign on to the coalition.
"do you really honestly think that, for instance, South Africa could attack Lesotho and just conquer it? And that everyone would just be like "oh congrats SA on adding a couple thousand square miles to your territory!""
Interestingly, Lesotho recently pleaded with South Africa to annex them.
Yes, you're right, conquest is not normal anymore. That doesn't mean that there is no possibility of conventional war between major powers, though. As I said, there are lots of cases of territorial disputes, and plenty of other reasons for war. We'll see how the norm against conquest holds up when oil and other precious commodities become increasingly scarce. Interestingly, this all relates to my research, as I'm talking about how the norm against conquest has made states in Africa and elsewhere weaker. Since conquest and war was a primary means of states becoming strong in Europe.
"They want them back, but they also don't want to go to war with us. That's why they haven't attacked yet. The longer this is the case they more likely it will be that China just accepts their independence and lets it drop."
There have been numerous close calls on Taiwan. As late as 1996, there was a military stand off between China and the US there. China will absolutely go to war to prevent Taiwan independence. THe reason they haven't invaded yet is because Taiwan hasn't been foolish enough to go that far. They were close under Chen Shui-bian, but now they have reasonable leaders and ties are improving.
"Japan and China are not going to fight. I don't feel I have to explain that one. You don't get anything out of winning a war against your neighbor like you did in the past. What are they going to do? Make them pay tribute? As if that will actually cover the cost of the war."
Why is tribute and conquered territory the other thing that can be won in war? Why wouldn't Japan want to reduce the power and influence of China in the region? Why wouldn't China want to eliminate a US client state that undermines their influence? The benefits of cutting a rival down to size might outweigh the short-term costs. That was our calculation with Iraq. The short-term cost of occupation would be outweighed by a stable, democratic Iraq that was a US client state and allowed US military bases.
"War is too expensive. We would only engage in it to, for instance, prevent someone from, say, using nukes or conquering a country, etc. "
Why would war being too expensive only prevent war between conventional powers? You talk about police actions, but these police actions are expensive too, and yet people engage in them. As I said, sometimes states believe short term expense can be overriden by the long term effects of victory.
"But that's where insane dictators come back into play. As it stands only NK in East Asia has an insane dictator. But even he shows signs of sanity, know that if he attacks SK the game is up and his rule is over. So instead he uses it as a threat, but it's a threat he can never carry out, because it would be the end of him."
NK is not "insane" at all. THey repeatedly called for a peace treaty with the US, which the US rejected. The US also promised 2 light nuclear reactors to help with NK's energy needs, the US never followed through (this was the 1994 agreed framework - build 2 reactors by 2002, never happened). The Americans and their UN "allies" bombed Pyongyang into the stone age in 1950, and never signed a peace treaty. Why on earth should they trust either the UN or the US, when they have thousands of soldiers stationed in South Korea?
No sorry, NK is very sane. They know that they will be continually attacked and provoked by the South and anytime they retaliate, the media will on cue call NK "insane" no matter what happens.
"People are not going to spend all that fucking money on a war to, say, for instance, get control of some fucking rocks sticking out of the surf.
This isn't 1750. lol."
China and India fought a war over control of rocks in 1962 (Arunachal Pradesh). 4,000 died. The UK and Argentina engaged in a bloody war over a largely uninhabited island in 1982. So you're wrong. The fact that we're in a number of 'police actions' points to the fact that expense doesn't prevent war.
