Harris' two war dilemma

The two wars in which we are now engaged (Israel/Hamas and Russia/Ukraine) would not have happened if Biden/Harris hadn't shown how weak this administration is back in August 2021. But that ship has sailed. We're in it now and half the country seems OK with that really poor leadership, exchanging a man who couldn't talk for a woman who is afraid to talk.

 
My question is why do Democrats/leftists seem so interested in some sort of negotiated peace for Israel/Hamas when Hamas and all radical Muslims have declared that Israel has no right to exist, but never even suggest that a third party might work with Russia and Ukraine to save lives and work through territorial disagreements. Neither war is in our best interest.

Does it go back to all those Ukrainian deals made by Biden's son when Joe was vice president? A lot of money changed hands. Or could there be growing anti-Semitism in the U.S., especially in the Biden/Harris administration? And what is the motive of people willing to vote for Harris to extend this mess?
