Saving US hostages in Gaza: Use Egypt as intermediary, urges Rep. Mike Waltz

American citizens are being held hostage by Hamas in Gaza. President Biden has said that the US government is pursuing all available avenues to bring them home. But how does that happen? US Representative Mike Waltz is a decorated veteran and knows how hard it is to pull something like this off in the middle of a war zone.

"I could just tell you as a former Green Beret that for a hostage rescue to be successful down in the tunnels where it is incredibly difficult to intercept any type of communications, GPS doesn't work, is quite difficult," he tells Ian Bremmer on GZERO World. "I mean, there is a reason Hamas has built this massive tunnel network. It's incredibly difficult to get to. They will constantly be moving them around. I mean, this is just a Gordian knot in terms of trying to get these folks militarily. So at the end of the day, we have, look, we have historic intermediaries."

But what happens when those intermediaries, like Qatar, are also housing top Hamas leaders? Tune into the latest episode of GZERO World for a full and nuanced episode on the ongoing crisis in Israel.
