alt Hacker NewsIt sounds like we have some common ground, but I think you may have a misunderstanding of the present American worldview and politics.
We're 79 years removed from Philippine independence, and you would have to try very hard to find a single American who wants them back. The US military would have been fully capable of annexing Iraq and Afghanistan with violent repression of dissent and zero concern for civilian casualties, had that been the will of the people. After 75 years of peaceful coexistence with a hypothetical independent California, I would be very surprised to see any political will for annexation.
The "same international norms as the rest of the world" you refer to are anachronistic. The post-WWII norms, to a large extent defined and upheld by the US, aren't based around maximal balkanization or unconditional support for separatism, but rather opposition to transfer of territory by force. If that sounds like ladder-pulling, maybe it is, but China has no standing to complain; Western conquests have been largely disbanded, while China remains as the third-largest nation in the world (ahead of the US).
I'm not claiming that the US has never done anything wrong. I asserted the opposite of that. I'm arguing that pointing out someone else's crime isn't a justification for someone to go commit a crime of their own. If you shoot someone from a rival gang, your lawyer isn't going to argue in court that it's okay because someone else from that gang shot someone else a decade ago. There's actually a word for that: https://en.wikipedia.org/wiki/Whataboutism.
But if we both agree that wars of aggression are bad regardless of whether they're started by the US, China, Russia, or anyone else, then we're basically on the same page.
I think that the American worldview is heavily propagandised and doesn't particularly reflect reality. The post WWII-norms are not at all a story of peaceful self-determination. The decolonisation of the Phillipines was an anomaly and an outlier. At the same time that the US was letting go of the Phillipines, it was gearing up for war in Korea on behalf of its puppet military dictatorship that was, at the time, even more repressive than the North Korean one. The Dutch fought a war in an attempt to keep control of Indonesia. France fought a war for its colonial possessions, which the US joined in on. Portugal fought wars for its colonial possessions. The UK let India go only because it was utterly ravaged by WWII, and they recognised they would not likely be able to keep it by force.
Moreover, the US specifically simply adopted a different model: puppet governance. As did the USSR. You would hardly find an American who would say that the USSR was benevolent, despite the fact that they believe themselves to be benevolent while doing the same things. Invading a country to install a regime loyal to yours is not meaningfully different from annexing the country outright. But it allows the populace at home to believe that they are doing the right thing. Why, their form of governance is the best governance in the world, so they're doing other nations a favor by invading them and replacing their governments!
Americans will make all kinds of fuss over China doing meaningless posturing in territorial waters, meanwhile their government is currently launching missiles in Venezulean waters, actually killing people. They violated the sovereignity of Iranian airspace, dropping bunker busters on government buildings. They assassinated another nation's top general. These are all acts of war. Nothing has changed. America continues to operate as it always has, under the principle of "might makes right", while dressing its operations up in pretty rhetoric.
Pointing out hypocrisy in ongoing international norms is not whataboutism. In a world where nobody is ever punished for shooting a rival gang member, then you either shoot or get shot; that is simply the natural way of things. And moreover, the prosecutor bringing charges against the Red Gang is a member of the Blue Gang that shot theirs first. Why would the Red Gang entertain, for a moment, the charges of aggression from the Blue Gang which did already intervene in its civil war and effectively seized territory from it? For the Blue Gang to possibly be convincing to the Red Gang, it would first need to make amends and to stop actively committing 10x worse crimes than the crime it accuses the Red Gang of. If we want a peaceful world, I'd argue the onus is on the US to live up to its self-proclaimed "rules based international order" first, because it is the one violating those rules the most, and other nations will not simply lie down and agree to be bound by rules that are openly being violated to their detriment.
I'm in agreement that wars of aggression are bad, but I strongly dislike the tendency for that to be selectively leveraged to paint only certain actors in a bad light. I think from a non-American perspective, it's pretty clear that the US is a much more egregious international actor than China. But if you agree with that, you're in a true minority of Americans. Even if there are a substantial portion of Americans who disagree with their own invasions, most of them will still see China as much worse than themselves, despite the fact that the PRC's last and only real invasion was the reclamation of Tibet 70 years ago, and otherwise it has only started a couple of minor border skirmishes for the entirety of its existence. Meanwhile Americans engage in Yellow Scare-esque fearmongering about China invading Japan which, as a neutral third party, seems so far outside the realm of possibility as to be utterly delusional.
