Ukraine was shelling civilians in Donbas from 2014-2022 - before the invasion. It was the key reason Russia gave for the invasion. That Ukraine shelling of civilians was a war crime - before Russia was in the conflict.

The OSCE (a western organization based in Vienna, not pro Russian) stated there were virtually zero (as in fewer than 50) Russian troops in the Donbas and Russia did not send weapons prior to Russia's invasion. Russia certainly had massive political influence, but not military presence. Both Donbas Oblasts asked to join Russia after the 2014 coup. Russia refused them for 8 years.

Your statements about weapons is half true. If they are so good, Ukraine would have driven out the much smaller Russian forces within a few months. With Russia still occupying about 20% of Ukraine, that clearly did not happen. I can look at a map and read Western reports and see that Ukraine is losing, despite Ukraine's very impressive victories in the last month.

Technically it was a coup. The democratically elected president fled the country under threat of death from armed insurgents. A replacement president and leaders named by the US (leaked phone transcript) were installed. That is a coup, plain and simple.

Your conflation of Ukraine, a neighboring country to Russia, with the US is risible projection. Russia is definitely a bully. A regional bully. The US is a bully that is about 100x larger than the Russia. A global bully. There are only three countries in the world that the US has not invaded or had a military presence in: Bhutan, Andorra, and Leichtenstein. The US has meddled, invaded, and/or attempted to overthrow (often successfully) 83 countries (IIRC) since WWII. The record of who is the "bully" here is clear.
