US cyber capabilities have an edge because they can analyze all of our data stored with US tech companies and they have interception points on all major internet cables.

Their human intelligence is much better prepared to "convince" someone to act against their own interest if they can look at your last ten years of communication, family pictures, and web browsing history before they even meet you.

Imagine working in a foreign country where death penalty is applied to certain crimes, like blasphemy or homosexuality. They just need to find one person in the target organization who has a secret twitter account that talked badly about god and then they hit them up and tell them to plug in a certain USB stick to a certain system. Cyber operation succeeded because they have a shell.
