There is no concrete evidence that Trump was aligned with Russia. That is as much of conspiracy theory as Obama was believed to be part of the New world order. Biden could not even fight the Talibans. When Russians saw Biden withdrew so desperately from Afghanistan, they were more than sure US is too weak to come after them at least for now. One can only speculate if this would have occurred under Trump, but the fact is this has happened under Biden and so far he has no guts to ban even the Russian oil.
