Gawd. There's no Trump lover, here.
As I said, the guy is a thug. He is clearly (as in, openly, not in code, no 4 d chess, just in extremely clear language) saying "If that was me, I would invade the Ukraine too. The gains are just too tempting, and no one is doing anything to make the costs prohibitive." That's literally what he said. And it's not to be taken lightly. As I said, he's an absolute wannabe strongman and, as such, he absolutely does think Putin is "Smart" to invade the Ukraine because that absolutely is what he would do in that same situation.
The message of which is NOT, "And so you should let him because I think he's cool" but rather (and again, very clearly unless you are obtuse, intentionally or unintentionally), "If you wanted me to stop, you would need to raise the stakes, and so if you want Putin to stop, you will likewise need to raise the stakes."
That's the very literal meaning of his messaging on Putin since the invasion.
