He's watched Sly Stallone in Over The Top too many times is all.
I can only speculate on how Trump figures to end this war but I don't see an expansion of it as is, either. Recent reports from ex NATO senior military officers and advisers indicate that this war has weakened Russia so much (in conventional military power terms) that there seems to be little prospect of her being capable of starting any more "special military operations" against other countries in Europe or elsewhere.
The main threat to Europe, is the use of nuclear weapons, especially if Putin's own top position comes under threat, I think that the Republicans recognize that danger far more clearly than the Democrats do.
