Trump Derangement Syndrome is not a 'rational' state of mind. It is a form of insanity.
TDS people will watch their home burn down before they would allow Trump to save it.
This is more or less what Zelinsky is doing right now.
But, for the sake of fairness, I am pretty sure Zelinsky hated Biden likewise, just not as much.
Zelinsky thought of Biden as a stupid old fool. But, he really 'hates' Trump.
Zelinsky wants the war to continue forever due to hundreds of billions and no elections. This is an unrealistic position. The war in Ukraine will end soon, one way or the other. If Zelinsky is determined to go down with the ship to f**k Trump, then that is how it will end. Zelinsky has made the call.
It is a shame. It is unnecessary. But, it is what it is.
