Two of the three Iowa Democrats running for the party’s US Senate nomination say American troops should not be deployed to Ukraine — but candidate Mike Franken says if Russia uses nuclear weapons, plans should change. Franken, a retired Navy Admiral, says the United States and like-minded countries must respond to help pick up the pieces if there’s a nuclear strike on Ukraine. Candidate Abby Finkenauer, a former congresswoman, applauds the sanctions the US and its allies have imposed on Russia and she supports providing Ukraine with the weapons and humanitarian aid it needs. Candidate Glenn Hurst, a physician from Minden, says the focus should be on working with European allies to support Ukraine and on resettling refugees in the United States.
