I think I may have already made the points that I was trying to make, to whatever extent, that anyone is going to listen... But then I saw this short and powerful essay by (yes, nominally leftist) former New York Times and The Nation Magazine opinion writer/columnist/reporter, Chris Hedges.

I think it's quite good. Humor me, and give it a read. It's quick.
As to the two items above - The PLA is only in the West Bank as I understand it. The money is delivered in ways that are designed to prevent the Palestinians from buying weapons, anyway. At the time Trump did that, I thought it was unconscionably cruel and callous. The people relying upon that aid were deeply affected - unto death in many cases. 'Sorry - no money for your insulin or cancer treatments. Learn to get by with less of everything.' It sadly wasn't out of character for Trump, who is an Uber Zionist, and has not only exhibited-, but promoted-, antipathy and hostility towards muslims* -which many Palestinians aren't, btw.
As for those Billions to Iran... It was ALWAYS THEIR MONEY, as a legal matter. So he just agreed to return the money that we'd stolen from them, going back to Reagan or Carter. And in exchange - he got them to enter a deal not to pursue Nuclear weapons - which actually isn't such a great deal, because they had no real intention of getting them. They consider them "unIslamic" - because they kill indiscriminately.
There's no proof, yet offered, that any of the money released by Obama was used, or that Iran actually helped Hamas - which I think is a Sunni organization, where Iran are Shia. More likely Hamas got help from some Gulf Monarchy(s).
I did hear talk of Hamas saying that they bought some of the weapons they used, from corrupt Ukrainians, however.
