What part of "no one should be blowing anyone the fuck up" is so hard to comprehend? Stop fucking shooting explosives at human beings. There are no further qualifiers necessary. If your strategy for stopping Israel involves killing Israeli children, it's a shit strategy.
The USA should give Palestine an Iron Dome then
Too bad the Palestinians have not figured out a way to blackmail US politicians. That might put them on the road to acquiring their own Iron Dome. Something tells me they'd appreciate being supplied food and medicine first.
Or, you know, stop the nation bombing Palestine and throw all those war criminals doing it in jail. But yes, a system to stop Israeli bombs from committing genocide in Palestine would also be welcome.
