Afghanistan: Every NATO member went because of article 5. The Taliban explicitly refused to comply when requested to hand over Bin Laden. This is as clear cut casus belli as it gets. And then Australia, South Korea, Malaysia, Azerbaijan and even Mongolia participated. How are those NATO? How is Mongolia even aligned with the US or under their influence in any way?

Iraq: Japan, Australia, Nicaragua, Philippines, Ukraine, Georgia... And I'm leaving like a dozen non-NATO countries, aligned AND unaligned with the US, that took part in the invasion or post-invasion missions. I don't agree with it, and while there were numerous lies to sell the invasion, equally numerous countries were unhappy about UNSCR 1441 being treated like toilet paper by the UN itself. Moreover, actual major NATO countries like Germany or France were diametrically opposed to the invasion and told the US to take a hike.

When you hold a hammer everything looks like a nail.
