Zelensky hung drawn and quartered but why?

By comparison with the brutal treatment meeted out to President Zelensky in the Oval Office, Keir Starmer's somewhat touchy-feely session with Donald Trump now looks like diplomacy at the highest level. Poor Zelensky, after nearly three years of being lauded by all his fellow leaders in the West as the bravest man on the planet, he got bawled out by Trump and his sidekick, JD Vance, who seemed to have preplanned the onslaught in order to humiliate the Ukrainian leader in front of the world's media. It was painful to watch. So, what was it all about, was it just an opportunity for Trump to slag off Zelensky for not saying thank you enough times or was there some more devious strategy behind the unpleasantness? I suspect there may have been. Perhaps the idea behind the anger and insults was to make Zelensky panic and tremble to such a degree that in a few weeks or months he will come back to the White Office begging for a peace and minerals deal whatever the consequences for him and his country. Then Trump can claim total victory, keep Putin happy and stop the war. Once that's done, then he and Putin can get down to even more serious negotiating about improving relations, making further cuts in nuclear stockpiles, removing the nuclear threat from Iran and getting rid of all the nasty sanctions Russia has been enduring for years, plus, of course, lifting the warrant for Putin's arrest on war crimes charges. First has to come the peace and minerals deal but on Trump's terms, not Zelensky's. So, under this plan, Trump will be expecting a begging letter from Zelensky in the not too distant future. That, I think, is what it was all about.
