So we have to make sure that most of the world implements these taxes

Arent we already trying?

Tax havens should be ostracized.

In this specific case, there's no need for a communist revolution, just political will to change something, diplomacy and unwillingness to budge towards countries who don't want to play fair.

The people everywhere already try the diplomatic way, but breaking political will with capitalist media is part of the counter Offensive of the Bourgeoisie against the reformist struggle.

The need to Organize is equally important in reformist battles as in revolutionary Battles. Furthermore, the dependancy of the plan on global scale action means organization of scale unheard of in human History.
