Speaking at a special session of parliament Monday, Ehud Barak, Israel's defense minister, said the country is engaged in a "war to the bitter end" against Hamas in Gaza but declined to give details of how far that war would go to stop Hamas rocket attacks.
Barak is a candidate in Israel's election. Former Prime Minister Benjamin Netanyahu, the current front-runner, hinted at a broader campaign to end Hamas' rule in Gaza.
Netanyahu told Reuters today that a government under his leadership would use "all means necessary" to end Hamas' rule in Gaza.
And in an interview with Fox News, he said that to truly eliminate the threat of rocket attacks Hamas "will have to go." Ending the threat once and for all "will entail bringing down the Hamas regime sooner or later," he said. Israeli elections are scheduled for Feb. 10.
Israeli tanks remain poised on the Gaza border, waiting for the call. At this point, there seems to be no end in sight to the Israeli operation.
