What is globalism and what do you think of it?

I hear 'globalism' being used as a term from Trump supporters who see the fight within the Republicans as being between the 'globalists' (mainstream Republicans) and the 'nationalists' (Steve Bannon fans). This always seemed strange to me because to use globalist as a term of criticism has normally been the preserve of the political left, using it to define the power of international capitalism.

It seems to me that the nationalist right also (kind of) mean the same thing, but also linked to a cultural critique of what they see as forced homogenisation of essential national values. Instead of a class analysis, they have a theory of liberal elite takeover or 'Cultural Marxism'. Ironically given that Marx himself was mostly concerned with writing about the power of elites and capitalist power, their own critique of cultural Marxism is in itself a bastard child of Marx.

I am not saying that the radical left or the radical right are the same, far from it. I would side with the moderate centre against the radical right on any single day. Both left and right have different analysis and different solutions. The one common thread is that both are against the current system of international capitalism or neo-liberalism.
