Actually, Joe Biden only named one logical consequence with his unplanned sentence at the end of his speech in Warsaw: when Vladimir Putin finally unmasked himself as a “war criminal” and “butcher” with the murderous attack on Ukraine that violates international law, as the American President did had previously announced without contradiction, then as a democratic and freedom-minded observer of the Ukraine war one can only agree with Biden: "For God's sake, this man cannot stay in power."
Only Joe Biden is not an observer, but supreme commander of NATO supremacy.
That's why every word counts - which, by the way, no one pointed out more often than Biden in his election campaign against Donald Trump.
That the White House had to correct the president minutes later and insist that the United States was not seeking regime change in Moscow is more than just another embarrassment in the life of a president who once described himself as a blundering machine.
Biden has given the enemy an invaluable propaganda gift.
With the postscript, he practically denied his repeated assertions that the Kremlin was completely wrong in accusing NATO of “an imperial project to destabilize Russia”.
In the future, Putin will be able to use Biden's words to parry any statement that the West is only interested in defending democracy and international law in Ukraine.
The people in Germany and elsewhere in the West, whose skepticism about America is still far from being driven out by Putin's war, will presumably soon do the same.
Fight authoritarianism?
Biden trips himself
The glitch in Warsaw is therefore likely to undermine the unity of the Democrats on the side of Ukraine, which Biden had previously invoked in impressive terms.
The NATO allies will probably not be deterred.
But beyond the western world in the narrower sense, any claim that Washington should decide who gets to govern which country seems toxic - and not only since the war that began under false pretenses and led to the fall of Iraqi ruler Saddam Hussein.
Among the 141 countries that condemned Russia's attack on Ukraine in the UN General Assembly in early March, many will wonder whether they should continue to position themselves so clearly on the side of the West.
It is difficult to judge whether a negotiated solution of any kind between Kyiv and Moscow has moved even further into the future as a result of Biden's presumably thoughtless sigh.
The bitter news from the battlefields, from Putin's point of view, undoubtedly plays a much greater role in this than any words from the American president.
But Biden has done his own agenda a disservice.
When he took office a good year ago, he stylized himself as a general in the struggle between democracies and authoritarianism.
Above all, he had his own country in mind, which he wanted to bring back onto a democratic course after four years under the authoritarian Trump.
Biden also had in mind China's desire to impose its social model of bondage on the world.
For a long time, Russia was more of a sub-point in the Trump saga in this narrative.
But now there is war in Europe and Biden is in demand as the old-fashioned “leader of the free world”.
How he fares through this crisis will help determine whether the world's democracies pull together to defend the Western model against its powerful enemies.
