The text of article 5 doesn’t distinguish whether the attack on the NATO state was justified or even whether the NATO state attacked first.

This lack of blaming is partly why Turkey and Greece had to sign at exactly the same time, so that neither could take advantage of being able to attack the other whilst being themselves shielded by NATO.

Arguably, the text of Article 5 doesn't have to, since an act of aggression breaches the obligations of Articles 1 and 2, as well as the pre-existing obligations which the Treaty explicitly does not alter under Article 7.

I see what you mean - although articles 1 & 2 seem to be treated more like guidelines rather than rules.

Otherwise I struggle to understand how any NATO member could’ve engaged in any of the overt or covert expressions of military force in Iraq 2003, Vietnam, Cuba, Iran, Guatemala, Chile, Egypt, or Algeria to name but a few.

None of the conflicts you list were NATO actions.
