You are correct. Jordan took “Palestinians” in and “Palestinians” tried to overthrow the government. Lebanon took them in and the only Christian city in the Middle East,Beirut called the Paris of the Middle East, turned into an out house. Egypt dealt with them and the Egypt Gaza border turning into a smuggling den. The barrier between Egypt and Gaza is now the envy of every wall builder in the world. The foundation of the wall is 20 ft deep reinforced concrete. Hezbollah is an international drug smuggling organization. Let them in at your peril.
I find it amazing that terrorist supporters here in the USA protests, claim that Israel blocked Gaza from bringing in food and medicine (not true of Israel who brought in many supplies of food and medicine). And at the same time don't question how millions of pounds of munitions, guns, ammo, machine tools for producing rockets, were in Gaza and used to murder Israelis. They just magically appeared in Gaza. Thousands of mortar shells and rockets lobbed over the wall from Gaza into Israel. Seems that Gaza had no problem bringing this stuff in.
You cannot coexist with people who want to kill you.
