Not everyone thinks that President Biden's decision to pull all US troops out of Afghanistan by 9/11/21 is a good idea. Conservative Congressman Mike Waltz (R-FL), a combat-decorated Green Beret with multiple tours in Afghanistan, thinks that the US still needs to maintain a small presence in the country to avoid incurring "massive risks." In a spirited discussion with Ian Bremmer on GZERO World, Waltz, who served as counterterrorism advisor in the George W. Bush administration, argues, "The next 9/11, the next Pulse Night Club, which is right on the edge of my congressional district, the next San Bernardino, that's now on Biden's watch. He owns it with this decision." Their conversation is featured in the upcoming episode of GZERO World, which airs on US public television starting Friday, April 23. Check local listings.
