So why are Egyptian Muslims declining to help their Muslim Palestinian brothers?
Its easy,some quick history: In the late 1960s, Jordan invited Palestinians to come live in Jordan, to be “safe” from Israeli strikes, so how did the Palestinians repay this act of kindness, they tried overthrowing the King of Jordan, which led to the bloody Black September in which the Jordanian army killed 1000s of Palestinians.
Next stop, Lebanon then invited the Palestinian leadership to come live in Lebanon, just a couple of years later, Palestinians tried to overthrow the govt. of Lebanon, which led to the Lebanese civil war that killed over 120,000 people!
