"Every life is valuable! We condemn all forms of terrorism"

Zelenski has to walk a fine line ... on one end, he needs support from Israel, on the other, he knows Israel is an occupier just like Russia, so he cannot even show too much support. And so, he condemn "all forms of terrorism", implying that Ukraine, unlike Hamas, is not resorting to (too much) terrorism to fight back ... between a rock and a hard place there.

Or he could just condemn Israel and lose their support, in exchange for "the moral high ground" and avoiding hypocrisy, but that never won any war. I don't envy him.
