How many countries has China invaded or bombed from afar in the last forty years? How do China’s loan conditions compare to those of the World Bank and IMF? The notion that they’re “colonizing” anyone is completely daffy - they have long-running border disputes with some of their neighbors and a long-running leadership dispute with what remains of the previous government of China, those are completely different types of conflict.
As for Russia and Israel, the difference is that the people in the Donbas who seceded from Ukraine back in 2014 weren’t placed there to displace Ukrainians as a Russian colonial project. They’re the same people who lived in Donbas going back to the USSR’s dissolution, and they had a series of legitimate grievances when the rest of Ukraine elected a government that was actively hostile to them.
Always worth bearing in mind. The reason Crimea got taken over in 2014 and Donbas didn’t is pretty clearly because of its relatively higher strategic importance - it took a lot of provocation from NATO and Azov for Putin to change his mind about that calculation, I’ll never forget how bloodthirsty the media was especially in the month leading up to the invasion.
