The Republicans' whole strategy is to end the war in Europe, get the Europeans to pay for security, normalize relations with Russia, try to "reverse Nixon" them if possible, and pivot completely to China.
You have to understand their mind set - the conflict with Russia is a "family conflict," but the conflict with China is an existential, racial conflict. The white man's supremacy must come before anything else - to be under another race's feet is intolerable.
Almost no other civilization on earth thinks like this. Yet it has been the philosophical model of Europeans for many centuries.
"I think we shall have to take the Chinese in hand and regulate them. I believe that as civilized nations become more powerful they will get more ruthless, and the time will come when the world will impatiently bear the existence of great barbaric nations who may at any time arm themselves and menace civilized nations … The Aryan stock is bound to triumph." - Winston Churchill, "hero" of the West
In other words, it is the duty of the white man to knock down any challengers to his supremacy.
