“Two things are true: Israel must do something, and what it’s doing now is indefensible.” So writes Zack Beauchamp, a senior correspondent at Vox.

Almost a month has passed since Hamas fighters slaughtered over 1,400 people in Israel and the state mounted its furious response. For weeks, Israel has laid siege to Gaza, cutting off water and electricity to the tiny strip of land and carrying out airstrikes that have reportedly killed over 8,000 Palestinians. On Friday a ground invasion began, and the response across much of the globe has been horror. If Israel continues down this road, the cost in Palestinian lives, and in support for Israel, will be immense.

The question that hangs over the criticism is this: What, then, should Israel do? What would be a moral response to Hamas’s savagery and to the very real need Israelis have for security?

Beauchamp, who has covered Israel extensively in recent years, set out to answer that question. He spoke with counterterrorism experts, military historians, experts on Hamas, ethicists and more. I found his piece “What Israel Should Do Now (https://www.vox.com/2023/10/20/23919946/israel-hamas-war-gaza-palestine-ground-invasion-strategy)” one of the best I’ve read since Oct. 7. So I asked him to join me on the show.
