I guess the US has more luck running a case where they have access to one side at least but it’s not like this does anything as the US has no power to charge Russian citizens not in the US. Like this would sound more meaningful if the US worked with international institutions for this like the International Criminal Court in Hague for example.
Been to Russia and live on the border of it. Basically if you have a chance of beating Putin you aren’t going to be an option to vote for. The part of the government who decides who will be the options is controlled by Putin. The approval is pretty much bullshit, I haven’t asked everyone in Russia but I have yet to meet someone who supports Putin, especially after he invaded Ukraine.
