WTF - US Senator Roger Wicker, (R - Mississippi) says Biden ‘shouldn’t rule out nukes’ against Russia

Never publicly "rule out" any option.
It doesn't matter what Biden says anyway, it matters what he will actually do, and what Putin believes he will do.
Unfortunately, the answer in both cases is "probably nothing"; nothing effective, anyway.
Russia needs a deep sea port that isn't frozen-over all winter.
And they'll get it.
