The Costs of Not Supporting Ukraine Far Outweigh the Costs of Supporting It

David Rothkopf: A growing number of Americans believe that U.S. is giving too much to Ukraine.

He says a decline in American support for Ukraine would reinforce Russian President Vladimir Putin's view that America and the West will tire of the conflict and withdraw from it, leaving Ukraine to his tender mercies.

But reducing support from Europe will result in diminished Ukrainian capacity to resist Russian aggression, he says.

Rothkowski: Less American aid to Ukraine will not necessarily induce Putin to stop raising specter of nuclear war.
