Re: "extended stay in shelters.”
"When they threaten Israel, Hamas really underscore how much they are powerless"
Which is exactly why the only way Palestinians will get anywhere is by non-violent resistance Ghandi style. Currently Israel has the luxury of the excuse that they are protecting themselves from a deadly enemy who wants them dead, while at the same time they are so much stronger than this enemy that their casualties are minimal, they take land from Palestinians at will, bulldoze their houses, build walls around etc, all can be doen in the name of their own security.
If Palestinians use a non-violent strategy, Israel will no longer have any excuse for what is a blatant land grab. It's a long-haul strategy and a tough one to keep to after all the violence there, but the only one that has a chance of succeeding. Hamas can never win a physical fight vs a far stronger Israel.
