I don’t think it would go over all that well. Americans don’t care about the Ukraine despite endless media coverage. Starting WW3 over that hell-hole would not exactly play well with most voters.
The corrupt politicians do not want ww3 as it would interfere with the money laundering.
The Russians have been in Ukraine for 8+ years.

This is a never ending war that the USA and europeon politicians can launder money in.
