Israel’s impending Gaza invasion: a moral quagmire

When you're fighting a monster, don't become one. The world is watching and wondering as Israeli troops prepare for an all-out ground assault on Gaza. Still reeling from a Hamas' horrific attack last week, there's an understandable desire among Israelis to push back hard and make Hamas pay. But what about the 2.3 million Gazan civilians caught in the crosshairs?

"I'm not sure how to say this," Avi Mayer, editor-in-chief of the Jerusalem Post, tells Ian Bremmer on GZERO World. "Obviously the residents of Gaza are not all responsible for the actions of Hamas. I think that goes without saying, and it would be absolutely tragic if the human toll on the Palestinian side kept mounting as a result of Hamas' murderous actions. But at the end of the day, Israel needs to do what it must to keep its own people safe. That is its number one priority."
