One at a time CC, You are prone to avoiding questions by asking another question:

"Why shouldn't they have weapons?"

The question was why would they buy weapons instead of food? Why would they spend food money on weapons and them claim they are starving?

Why do they have to smuggle food in through tunnels? Is food illegal or something?

The answer to your smoke screen question is yes, they can have weapons as long as they use them for defense and if they do not fire missiles into another country to deliberately cause themselves to be invaded like they have engineered. Then they whine a cry and suck snot to gain sympathy from idiots to make the Jews look bad.

The blockades are for weapons, not food.

The tunnels are for smuggling weapons, not food.

"When Fatah tried to stage its coup in all of the Palestinian areas, it only succeeded in the West Bank, but not in Gaza"

More evidence that Palestinians want to fight, they do not want peace.

The fighting continued into 1971, however, when King Hussein finally struck a decisive blow against the Palestinians, driving them out of their remaining bases and expelling them from the country. The Palestinian extremist group Black September was named after the month in which the Palestinians were driven out of Jordan.

Yes, they were driven out of Jordan, Jordan did make peace with Israel and Jordan is a trading partner with Israel.
