At about 2 a.m. last Tuesday, Republican Sen. Ron Johnson of Wisconsin stood on the Senate floor and explained why he opposed sending more aid to help Ukraine fend off the invasion launched in 2022 by Russian President Vladimir Putin.

“I don’t like this reality,” Johnson said. “Vladimir Putin is an evil war criminal.” But he quickly added: “Vladimir Putin will not lose this war.”

That argument — that the Russian president cannot be stopped so there’s no point in using American taxpayer dollars against him — marks a new stage in the Republican Party’s growing acceptance of Russian expansionism in the age of Donald Trump.
