I have to say Biden's comment was pretty fuking stupid. Putin will be looking for every excuse he can lay hands on to bolster his position in the eyes of his people and having the "enemy" saying they want the head of state out just plays into his hands - staggering ineptitude.
Why did the White House intervene after Biden's speech?
"For God's sake, this man cannot remain in power", US President Joe Biden said about his Russian counterpart President Vladimir Putin during a speech in Poland's capital Warsaw on Saturday.
This was quickly followed by the White House saying Biden wasn't calling for regime change, but was instead making a point about Putin not being allowed to exercise power over his neighbours.
This was clearly an attempt at rolling back - the concern is that this is going to put more pressure on Putin and make him more uneasy.
Given that he is the head of a country that is struggling militarily, and is in control of a nuclear arsenal, the concern on the Americans' part is that they don't want to back Putin into a corner.
Calling out for regime change directly could cause instability and increase unpredictability.
And the last thing you want in these circumstances is unpredictability.
