I'm sceptical. Even if somebody would present a working fusion reactor today, what would the timeline to replace everything based on fossil fuels even be? Build several thousand of expensive fusion reactors in every country of the world, even in geopolitical rivals like China, Russia or North Korea or war-torn third world countries? Replace every car with an electrical one? Replace home heating everywhere? Rebuild every ship and airplane worldwide?
If there were a practical fusion reactor shown today, it'd be 10 years before it could be started to be deployed at commercial scale.
More to the point, fascism isn't going away just because we have better electricity sources. Cheap power is a problem in capitalism.
