The real enemy in Gaza is Iran

If Israel successfully overthrows Hamas in Gaza, it would strengthen anti-Iranian forces throughout the Mideast and signal the region that Iranian momentum can be reversed. The Israeli military operation could begin the process that topples a terrorist regime that seized power in the Gaza Stripin 2007 and has fired thousands of rockets and mortar shells into Israeli neighborhoods.

And whether or not Hamas is ultimately overthrown, Israel can achieve substantial goals. The first is an absolute cease-fire.
