5 compel another State to undertake or desist from a specific action, in matters falling under its domain réservé. The accelerating pace of technological change, the unpredictable effects of its applications, as well as the difficulty to measure the coercive impact of influence activities, which are on the rise, cannot be overlooked. Therefore, Italy sees merit in continuing to deepen the study of possible violations of the principle of non-intervention in cyberspace. That is particularly the case with regard to influence activities aimed, for instance, at undermining a State’s ability to safeguard public health during a pandemic, or at manipulating voting behaviour.
