FROM Richard Allen
An Earthquake Early Warning System for California? All Californians know they're vulnerable to the Big One, but we're way behind Japan —even Mexico — in developing an alert system. But 30 scientists, working on a shoestring budget, are developing ShakeAlert at the US Geological Service, Cal Tech and the University of California, Berkeley. Richard Allen directs UC Berkeley's Seismological Laboratory.
The longest US war: Will Trump send more troops to Afghanistan? The Trump White House is divided over the Pentagon's request for more troops in Afghanistan—where the US has been fighting for the past 16 years. Is there a formula -- either for "victory" or a political settlement? Is there an end in sight for America's longest war?
What happens when America retreats from the world? Is President Trump taking his "America First" agenda to extremes, withdrawing the country from the international stage on trade and climate change, distancing America from its traditional allies across the Atlantic and even threatening to physically isolate the country through the building of a wall along its southern border? León Krauze guest hosts.
