Without being a Russia shill I think that Russia will have a large industrial base, and battle-hardened military and a population ready to fight and absorb the costs of war.

If Trump cedes Ukraine to them, they'll likely absorb it and turn the population to their side in the coming decade. At the same time it will have been established that the's no international rule of law and borders are based on strength, not global agreements.

They will have very little financial interest and soft power in the Western world.

If this holds true, I would argue they'll likely be one of the strongest military powers in the coming decade.
