The 'Palestinians' supported the wrong side. They lost some property. The Arabs did it again in 1967. They lost more property.
Luckily for them, they gained much more property and wealth from the Jews of the Middle East, when they ran them out of their homes in the hundreds of thousands... and those Jews had ACTUALLY been there for thousands of years.
But no one cries for them, because they were resettled in Israel, by a sane, humane, moral, just, modern society.
The 'Palestinians' should be resettled as well, in the 99.99% of the Middle East still under the control of Arabs and Muslims.
Or they can just keep fighting for that little 0.01% they lost (and never had a right to have to begin with)... and risk losing the other 99.99% in a nuclear meltdown.
On this you're wrong. On everything else you're right.
