Sen. Saxby Chambliss, the ranking Republican on the Senate Intelligence Committee, said on Sunday that Israel might have to invade Gaza to protect itself from further rocket attacks.

"The problem the Israelis have is that these rockets are being fired on them, from places that they can't reach by flying over in the air," Chambliss, a Georgia Republican, said on Fox News Sunday. "They are putting them in school yards, where they are surrounded by schoolchildren, and firing them from marketplaces crowded with people."

He said that, because Israel has the right to protect itself, a ground invasion might be needed. "If sending ground troops is the only way they can clean out these nests of rockets being fired at them, you can't blame them for doing it," he said.

Sen. Joe Lieberman, I-Conn., said that a ground invasion was not wanted by either side, but that the outcome was up to Hamas.

"I don't think Israelis really want a ground war," Lieberman said on Fox News Sunday, adding that, "The decision is up to Hamas, as to whether there will be a ground invasion of Gaza or not."
