Yes I agree with everything you've said.

I think it's worth adding that we also need to be aware that in any multipolar world, preferable as it may, or may not, be, it is perfectly possible that other spheres of influence around the main poles develop imperialist positions. I personally think that Russia has already well displayed this capacity. It's interests as a nationalist state capitalist power will naturally drive it to an imperialist position in its region of influence, imo.
