One piece of evidence would be that Russia, Belarus and North Korea have been specifically excluded from US tariffs. You could argue that the net effect is negligible since we don't import a lot from those countries, but the signal being sent to long term allies is devastating to America's future relations with them.
Iran is on the tariffs list because of Trump's maximum pressure policy (an official National Security Memorandum) against Iran. This is coupled with Trump's willingness to get Russia to cooperate in the ceasefire.
I'm not claiming his administration's logic is 100% sound, only that there is an explanation that doesn't assume the rather farfetched theory that Trump is an agent for Russia.
I'm not particularly well-versed in this area, but searching for the topic on Google easily found this information on sites such as Wikipedia, WSJ, Newsweek, and whitehouse.gov.
Yes, there is a LOT of evidence of this allegiance, although maybe just observing Trump's unwillingness to openly criticize Russia and Putin is highly suspect by itself.
If you're going with the great conspiracy of GOP as Russian assets, you should also add Elon Musk and the other tech robber barons as Russian assets as well.
To be clear, I meant literally compromised. As in, their machines are pwned. The whistleblower indication of Russian IPs logging in immediately after creation of usernames/passwords is a clear indication of that.
Musk seems to just have "small dick energy", or in proper words, a very fragile ego. And he seems to hate the "woke left" for "poisoning" one of his kids' minds that came out as trans. And like a 12 year old, his ego told him that anything the left is for, he'll be against...
Is there something about Elon Musk and the other tech robber barons being russian assets as well that makes the whole notion stupid on its face? I can't tell what your point is. Are you being dismissive or do you just want to remind people about the tech robber barons as well?
