There must be some truth to at least some of one party's claims

There's your first mistake!
There was NO "truth" in the Russiagate files. None. Every bit of it was faked by Hillary's boys. They'd done it before! The exact same thing: made a "dossier" of crimes, fed it to a willing press & the candidate was forced to drop out.

Nothing Hamas says is true. They have lied about everything for the entire time they (and the PLO before them) have existed. Why? Because Allah told them to. It is not a sin to lie to infidels, or to rape them, or to kill them, especially the Jews. It is required to bring about the 12th Caliphate & usher in the leader who will unite Islam under his (not hers, not theirs!) banner and subjugate the entire planet.
If Allah tells you to do it? You do it "with gusto!"

Just one example: Hospital bombed by IDF helicopter (or jet bomber, or missile, the story was ever evolving, eh?) in the middle of the night and 500 killed! An entire wing destroyed! They printed the names the next day, it must be true!

Reality: a mis-fire from a Hamas group's rocket barrage fell on the hospital parking lot. It was live-streamed by Al-Jazeera! There was a tiny "crater" and a few burned cars, that was it, it didn't even break any windows of the hospital. If anyone was killed it was because they were in the lot watching the rockets being launched & praising Allah for it.
& etc.
