I’m certainly not interested in defending Trump. I agree that he is dangerous, and I think pressuring him to continually escalate a cold war with a nuclear superpower makes him more dangerous. Leaving aside my opinion that Russiagate is bogus, Trump will never be impeached for Russian collusion. If any evidence for that existed to be found, it would have been picked up by the sprawling surveillance networks of the US and its allies and leaked to the Washington Post in 2016. All Russiagate gets is the Russia escalations the US defense and intelligence agencies have been after since the fall of the Soviet Union.
