What do you specifically mean? I just said Imperialism defeats itself, and people in the Global South can act against it by protecting their own production and resources.
They do. Supporting movements in the Global South against Imperialism by the Global North. Looking at the nature of Imperialism dialectically, it appears to be deteriorating as exploitation increases, so these movements are gaining momentum. This is what I mean when I say Imperialism defeats itself, as exploitation increases (as it must to counter the Tendency for the Rate of Profit to Fall), it also increases pressure against itself from those it exploits.
