It's up for the attacked (the US) to decide when the line is crossed and how to respond. Russian strategy is to confuse as mush as possible possible. They do cyber attacks, assassinations and political operations in the western countries.

Is hybrid warfare a warfare until it includes conventional warfare in the mix?

https://en.wikipedia.org/wiki/Hybrid_warfare

> Hybrid warfare is a military strategy which employs political warfare and blends conventional warfare, irregular warfare and cyberwarfare[1] with other influencing methods, such as fake news,[2] diplomacy, lawfare and foreign electoral intervention.

> The U.S. Army Chief of Staff defined a hybrid threat in 2008 as an adversary that incorporates "diverse and dynamic combinations of conventional, irregular, terrorist and criminal capabilities".[9] The United States Joint Forces Command defines a hybrid threat as, “any adversary that simultaneously and adaptively employs a tailored mix of conventional, irregular, terrorism and criminal means or activities in the operational battle space. Rather than a single entity, a hybrid threat or challenger may be a combination of state and nonstate actors".[9] The U.S. Army defined a hybrid threat in 2011 as "the diverse and dynamic combination of regular forces, irregular forces, criminal elements, or a combination of these forces and elements all unified to achieve mutually benefiting effects".[9] NATO uses the term to describe "adversaries with the ability to simultaneously employ conventional and non-conventional means adaptively in pursuit of their objectives"
