The lesson of the 20th century is that putting “America First” requires us to project strength and deter our enemies from launching wars of aggression — so that U.S. troops to don’t have to fight and die in another global conflagration. The invasion in Ukraine was a failure of deterrence. Only by helping Ukraine win can we prevent further deterrence failures.
If we help Ukraine prevail, we can rewrite the narrative of U.S. weakness; restore deterrence with China; strike a blow against the Sino-Russian alliance; decimate the Russian threat to Europe; increase burden-sharing with our allies; improve our military preparedness for other adversaries; stop a global nuclear arms race; dissuade other nuclear states from launching wars of aggression; and make World War III less likely.
The “America First” conclusion: Helping Ukraine is a supreme national interest.
