When you go near a Pro-Hamas (Formally called Pro-Palestine) protest in your city or university, you can sometimes here, “From the river to the sea, all of our people will be free.”

what dose it mean?

Well let’s brake it down into 2 parts
From the river to the sea = Distraction of the state of Israel
All of our people will be free = Hamas will be free to rape & slaughter Israeli civilians

People who say that usually stand with

Hamas

Hezbollah

ISIS

Russia

IRGC

Houthi
