ministry of state security. government agencies. i wouldn't impact the chinese population. that's bound to have a rally around the flag effect and maybe incite the chinese population against the u.s. >> in your new book, you argue that while the u.s. is focused on building up military-strength rivals such as russia and china are more focused on other kinds of attacks. cyberattacks, propaganda, disinformation. is the united states in any way prepared to deal with those threats from the chinese and the russians and iranians and north koreans as well? >> i don't think so. i think particularly when you look at the u.s. department of defense, a lot of the focus on the war games are a big conventional fight with the chinese over taiwan. and i think what these actions really show is where the chinese are coming after us is not an invasion of taiwan. where they're coming after the u.s. is on an economic side, the broader espionage side.
