Uk didn't invoke article 5 over Argentina, but you are missing the main point,,,ALL manufacturing Countries say how their weapon systems can be used, France is no different to the US in this way
You will note that the Pakistan's F-16 didn't attack India this time, The US has a veto on Pakistan for its use to attack India, The situation would have to have US approval to use it in an attack on India and override existing EUM
"The United States imposes strict restrictions on Pakistan's use of its F-16 fighter jets through End-Use Monitoring (EUM) agreements, which function as a form of control or "veto" over how and where the aircraft can be deployed. These agreements ensure the jets are primarily used for counter-insurgency and counterterrorism operations rather than in conventional conflicts against neighbors like India. "
