Rand Paul describes bombing, capture, blockade, Rubio says it still does not qualify as war

Factcheck, straight up:
Under international law, Rubio’s answer does not hold. Article 2(4) of the United Nations Charter explicitly prohibits the use of force against the territorial integrity or political independence of any state. Bombing air defense systems is a use of force. Capturing and removing a sitting president constitutes an armed attack and regime seizure. A naval blockade is itself legally defined as an act of war under the San Remo Manual on Naval Warfare and has historically triggered formal war declarations, including by the United States. Each element Rand Paul listed individually qualifies as an act of war under established international and US military doctrine. Together, they describe a full scale invasion.
