This today from The New York Times:
Khaled Meshal, the political leader of Hamas, gave a defiant speech on Saturday, vowing to build an Islamic Palestinian state on all the land of Israel, the West Bank and the Gaza Strip. Speaking [in Gaza] before tens of thousands of supporters on the 25th anniversary of the founding of Hamas, Mr. Meshal said the Jewish state would be wiped away through “resistance,” or military action. “The state will come from resistance, not negotiation,” he said. “Liberation first, then statehood.” His voice rising to a shout, Mr. Meshal said: “Palestine is ours from the river to the sea and from the south to the north. There will be no concession on any inch of the land.” He vowed that all Palestinian refugees and their descendants would one day return to their original homes in what is now Israel. “We will never recognize the legitimacy of the Israeli occupation, and therefore there is no legitimacy for Israel, no matter how long it will take,” he said. “We will free Jerusalem inch by inch, stone by stone. Israel has no right to be in Jerusalem.”The time has come to implement as a response to this what's outlined in this recent S&F post.
