Saying that Putin shouldn't be in charge of Russia is not only true, but no surprise to any of the principals involved. Putin knows we want him gone. We know Putin has consistently tried to help politicians who have been anti-NATO and isolationist.
It would have been unwise to openly endorse regime change. But Biden didn’t do that - in spite of what people on the right and headline mongering members of the media are prattling about.
It's is not easy to remove a corrupt dictator (yet another reason I don’t want one anywhere) but it can be done. I respect Biden for making the statement and I suggest no one should believe that making the statement in anyway endorses the United States becoming directly involved in a regime change.
Sometimes, it's a requirement to state the plain truth.
