Hamas is improving its rocket technology, and will soon be able to hit "any target in Israel," Reuters quoted a senior member of the organization, Fathi Hamad, saying Friday at a rally in the Gaza Strip. Hamas Prime Minister Ismail Haniyeh, who was recently reported to have "gone underground" out of fear he would be targeted for assassination by Israel, also spoke at the demonstration. Haniyeh addressed the possibility of a large-scale IDF incursion into Gaza. "[Such an] operation would end in total failure for Israel, just like the rest of its operations in the past," Haniyeh declared. "Israel is living under a delusion if it believes that it can topple the Hamas regime in Gazaâ€¦ Even if Israel kills our leaders, it can't damage the purpose of [our] struggle," he continued. Hamas spokesman Sami Abu Zuhri also spoke about a possible IDF operation in the Gaza Strip, saying that Hamas was "in a war against the new Nazis." Zuhri's comment came after Deputy Defense Minister Matan Vilna'i said Friday that "as long as the rocket attacks escalated, the Palestinians are bringing upon themselves a bigger Shoah [Holocaust]."
