A steady buildup in Hamas' weapons arsenal and persistent rocket attacks on Israel is prompting Israel to consider "action" options, Israeli Ambassador to the US Salai Meridor said Tuesday. "Nobody, basically, is confronting Hamas," Meridor said in a breakfast meeting with 15 reporters. He described Palestinian Authority President Mahmoud Abbas as ineffective and said, "I wish reality was different." Meridor did not specify what steps Israel might take, but he likened Gaza, which is under Hamas's control, to southern Lebanon in 2006. The Israeli ambassador said Hamas has strengthened its arsenal with more powerful rockets, some of them delivered to Gaza from across the border with Egypt. He appealed to Egypt to cut Hamas off and said, "Israel will act if Egypt does not seal the border." "The closing of the border is an Egyptian responsibility," he said.
