9/11 was not a military action against the USA, and the invocation of article 5 by the USA was illegimate.
that's a surprising thing to hear. where do you draw the line between terrorism and war? I see a distinction without much of a difference.
It's wild to suggest that terrorism against the US should not be responded with by military action - it's only the degree and targets that should be under debate.
If you say "Deus Vult", you are a war hero. If you say "Inshallah", you are a radical terrorist.
The rules are quite simple.
