I would say that sowing chaos and undermining trust is more a function of polarization, more closely associated with misinformation and disinformation than foreign interference. Although foreign interference can, of course, support it, I think that's obfuscating the problem.
Look at Australia. Australia reorganized its national intelligence community precisely because of its understanding of foreign interference as advancing the interest of a foreign power, and Australia's perceiving itself as not having been postured adequately in its intelligence structure and posture. The United Kingdom has organized its community. In Canada, we have not, and I would say this is related to a misunderstanding of the objectives of foreign interference. A rereading of annual CSIS reports might be in order.
