Well, the number of wars and conflicts that the US, UK, France, Germany, or Italy (de facto NATO) have been part of unnecessarily since 1949 is above 12 (a dozen), but then again dozen isn't a rigorous quantifier, and I was careful not to use a precise number since I knew it was somewhere between 10 and 15 but couldn't be bothered counting for my message.
Except your number is way off, and has no connection to reality.
