Russian cyber weapons 'could do a lot of damage' in the US: Former counterterrorism czar

Clarke, who served as US counterterrorism czar between 1998 and 2003, also explained why China has never done significant damage to American cyberspace: Chinese authorities know that a major cyber attack against the US would trigger a "traditional" retaliation from the US: "bombs, missiles, ships and airplanes".

The former US counterterrorism czar has been warning about cyber warfare for decades, before it was fashionable. He thinks there are "clearly threats that will be worsened by artificial intelligence (AI) unless it's controlled and regulated".

Clarke is worried in particular about the prospect of "hybrid war", which uses disinformation and cyber tools powered by AI, as well as political subversion.
