If it would really come down to it, the West (i.e., basically the USA) would be able to stop Israel oppressing the Palestinians. So that is political. They can't do that in China (without triggering a nuclear war).
I don't know about the 1-child policy exception; apparently China's internal calculus was different then from now. It would be nice if you were more explicit about why you're mentioning this instead of conspiracy-theory-like urging readers to "do their own research".
That's right. The US is unable to stop the torture in China.
They don't want to stop the torture in Palestine. The people running our government have vested interests. Every politician ever must bow to AIPAC, and many politicians don't need to bow, as they have their own interest in Israel (they are Israeli citizens and can go there any time).
Now you have your answer
Remember when China introduced the 1 child policy? China allowed Uyghurs to have more to not impact their minority
Now you understand how geopolitics affect your view on countries, don't let the propaganda stop you from being a critical thinker
Think more and make your own research
