Because the Ukrainian people have no interest in killing their heroic president.
Do you think they do just because you made up that fantasy?
Since when were gay dancing, piano dick-playing, running-around-naked-in-grocery-stores, B-grade actors who put on fake military garb whenever there's a camera about considered heroes? When are grifting, corrupt lowlife and frauds like Zelenskyyyy considered "heroic?" When the vile, leftist/globalist press simply proclaims them to be so over and over and over again in support of one of their nefarious agendas?
Answer: Yes.
The Ukraine doesn’t have a President. It has an unelected dictator murdering scores of citizens on a daily basis.
