Putin promised not to kill Zelenskyy, former Israeli prime minister says

Naftali Bennett emerged as an unlikely intermediary in the war’s first weeks, becoming one of the few Western leaders to meet President Vladimir Putin.

"A former Israeli prime minister who served briefly as a mediator at the start of Russia’s war with Ukraine says he drew a promise from the Russian president not to kill his Ukrainian counterpart."

After this promise is when Zelenskyy put on his khaki and started to parade around. Not before ! He was hiding in his bunker before.
