Look at it from their perspective. The US has provided Israel with bombs and ammunition which they have been using on Palestinians for over 70 years. Look at the atrocities we are seeing. Now imagine what the world didn't see when the internet/smart phones weren't so readily available.
The question the US citizens should be asking is why do the majority of US congress members have dual citizens to Israel.
The US government is control by Zionists and are implicit in this genocide.
