The question is whether his words are to be taken seriously. Biden says he was speaking his mind and his heart. That may well be true. The problem is that, because he is president, many people around the word listen more carefully than he sometimes speaks,and can’t be entirely sure whether he is merely emoting or actually letting slip his administration’s real policy.
As a result, certain allied leaders have criticized Biden for his remark—most prominently, French President Emmanuel Macron, who warned the American president it would be unwise to “escalate” the war “either in words or actions.”
It’s a bit rich to scold Biden for escalating the war given his painstaking efforts not to trigger a direct conflict with Russia—even while Putin bombs and shells.
Macron does have a a point. If Putin ever feels compelled to seek a negotiated settlement to the war, he may restrain that impulse he may be slower to act on it if he thinks the war is about his own hold on power and that, if he stops fighting, his foes will move rapidly to chop off his head. Just a "Unwise Guy"s" thought.
