There was rather a lot of NATO coordination in the US-led invasions of both Iraq and Afghanistan. None of the military missions in these countries were in response to the Article V mutual defense clause of the NATO treaty. It's very easy to see how these operations (and therefore the NATO alliance) would be seen as aggressive to these countries.

The 2003 invasion of Iraq wasn't the same group as NATO. France and Germany opposed the US's "coalition of the willing". [1]
