In an interview on ABC's "This Week With George Stephanopoulos," Peres was asked whether Israel's goal is a negotiated peace or the removal of Hamas, considered a terrorist organization by the United States.

"We don't intend either to occupy Gaza nor to crush Hamas, but to crush terror," Peres said. "And Hamas needs a real and serious lesson. They are now getting it. We were careful. We were restrained. We waited. We gave them many chances."

Peres said Hamas had taken over power in Gaza illegitimately after Mahmoud Abbas was elected president of the Palestinian Authority with 62 percent of the vote.

"Anyway, we are not going to mix into their politics, but we have decided not to permit to shoot against us," he added.

When asked Peres about Hamas's victory in parliamentary elections, which triggered a U.S. and Israeli boycott, the president said Hamas is allowing its people to be used by another country, Iran.
