What do you mean when you chant "From the River to the Sea, Palestine will be Free"? History lesson: it is the motto of Hamas, the genocidal terrorist group that has ruled Gaza since 2007, after Israel completely retreated in 2005. Since 1964, the slogan has embodied the motives of the PLO calling for the 57th Islamic state and completly eradicating the State of Israel in the process. And it is explicitely outlined in the Hamas charter, where article 13 says Jihad is the duty of every Muslim, and article 15 calls for the ethnic cleansing of every Jewish man, woman and child from Israel. This is not a message. It comes directly from the mouths of the Iranian Ayatollahs and Hamas and Hizbollah leaders. Every single such chant, anywhere, is an endorsement of that slaughter.
