Comments: Among the courses, the intervention of John Strand will teach how to attack the attackers, how to implement offensive countermeasures. There is no legal framework for such offensive activities, but "Well, to be honest, you will need it someday"...and "the old strategies of security have failed us and will continue to fail us unless we start becoming more offensive in our defensive tactics". That is what we call escalation of violence. Is this the unique solution to the current asymetry that provides advantage to the attackers? Might the State let private actors launch counterattacks against foreign actors?
