The biggest threats to US national security, foreign and domestic

Less than a month ago, the Biden administration finally dropped its long-anticipated National Security Strategy. The No. 1 external enemy is not Russia but rather China. It also emphasizes the homegrown threat of Americans willing to engage in political violence if their candidate loses at the ballot box.

On GZERO World, Ian Bremmer speaks to New York Times national security correspondent David Sanger about the key national security threats facing the United States right now.

Sanger believes the biggest threat to America's national security right now is an "insider threat" to the stability of the election system coming from Americans willing to engage in political violence. Taiwan's status as a semiconductor superpower may be staving off a Chinese invasion.

On Russia, Sanger believes that Ukraine and the world face the paradox that the better Ukraine gets at resisting Russia, the more likely Putin might launch a tactical nuke. And if he does, he might just get away with it.
