If you want a mass movement, you need an enemy to focus animosity on. For Hitler, it was Jews. For the Ayatollahs it was the Great Satan. For Democrats, white supremacy. The requirement for an enemy is that it is large enough to be unable to be beaten, while being small enough that beating it can be imagined. Climate change and Russia are the same type of enemy. Too big to beat, but small enough to think they can be beaten. Read The True Believer by Eric Hoffer. Way smarter than Saul Alinsky who probably also read it.
Brilliant.
