Isolating the US and breaking US hegemony. Trump is a Putin puppet, and what’s best for Russia is crippling the US economically and diplomatically. Alienating the EU cuts off the EU from the US who would otherwise help the Europeans against the Russians as they try to reclaim their former territories.

This also helps China who is trying to replace the US as the world superpower. BRICS is doing a good job of creating a competing economic alliance, and the US falling apart helps make it more attractive.

Not a conservative, by the way. Just someone who follows the news.
