As NATO gets bigger, especially given the recent war in Ukraine, it would seem that it would get more and more difficult to maintain a diplomatic consensus, seeing as the more members there are, the more scope there is for disagreement.
How does NATO ensure that all members agree on its response to potentially military disputes?
Two examples I can think of is the possible threat of armed conflict between two members, or where one member has a beef with a non-member that some of the others don't share. (e.g. what if Austria invaded Hungary, but Turkey believed that it was provoked or justifiable)
