Since you wrote this Russia HAS invaded. But you are wrong on a number of issues.

1.

Yes, the USA has a sordid expansionist and imperialist history. You accurately cite this history as if it is relevant to a Russian invasion of Ukraine. It is not. We can do two things at once- decry past US actions and still condemn Russian invasion of Ukraine ( as well as support Ukraine as they try to fight off the Russian bear ).

2.

Conquering Ukraine will NOT make Russia more powerful. It will make it weaker because how they will have added 44 million people under their control of whom 40 million do not want to be. There will likely be ongoing insurgency by armed Ukrainians, ongoing protests. All of this will be streamed live and recorded via the internet and social media.

3.

Regarding the supposed Biden agenda hidden like rabbits- the Ukraine war isn't about that at all- Go ask Manchin and Sinema as obstructionists to the greater good
