Andrew P. Hunter: “We just had an attack by people who did not care about mutually assured destruction.”

I think what today's hearing and what this situation and NATO's eastern flank highlights is the fact that we don't have a tremendous amount of time to wait around for the next great Army to show up in 10 to 15 to 20 years.

It is my belief that, collectively, NATO is not yet at a maturity level sufficient to effectively incorporate cyber technologies that exploit critical Russian infrastructure.

It is concerning; and, of course, it fits a pattern, a long-term pattern of efforts by China to obtain intellectual property and technology from the United States.

You cannot throw money at the problem, and we do not need to be investing government dollars where the private sector is going to invest its own dollars.
