The idea of nuclear deterrence—possessing weapons so that others don’t attack—doesn’t mean building up the arsenal makes us safer. Erin D. Dumbacher is Stanton Nuclear Security Senior Fellow and Director of the Defense and National Security Program at the Council on Foreign Relations.

Twenty-five years after the world-altering terrorism of 9/11, is al-Qaeda still a threat?

His article “The End of the European Summer” was published in The New Yorker.

Days or even hours before death, some dementia patients become lucid again – and scientists want to know why.

His article “Why Do Some Dementia Patients ‘Return’ Just Before They Die?” was published in The New York Times Magazine.

After the Sept. 11 attacks, the Federal government enacted laws that aimed at both protecting Americans and keeping tabs on what we do.

She joins host Krys Boyd to make the case that some of these laws have outlived their intended purposes and violate our liberties.
