Taiwan's secret shield against Chinese invasion: its semiconductor industry

The Biden administration has recently doubled down on its efforts to delay China's push to dominate future areas of tech by squeezing the supply of semiconductors Beijing gets from Taiwan.

Why? Because those tiny chips are "the greatest defense we have against Taiwan being invaded," New York Times national security correspondent David Sanger tells Ian Bremmer on GZERO World.

For Sanger, it's about time the US made such a move. America, he points out, was becoming as dependent on Taiwanese-made semiconductors as Europe was on Russian oil and natural gas before Vladimir Putin decided to invade Ukraine.

Still, he believes Biden's move will only buy the US some time if America doesn't build its domestic capacity to make chips.
