The question of a military conflict between NATO member states would have been an entirely hypothetical question a decade ago , but looking at certain NATO member states (e.g. Turkey) increasing alliance with Russia , it just seems plausible that there can be a military conflict in between NATO member states.
Here's an example - Some months ago , Turkey came very close to a military conflict with U.S. forces in northern Syria , Link - https://www.bloomberg.com/news/articles/2018-02-04/risk-of-conflict-in-northern-syria-between-u-s-turkey-rising .
Organisations like NATO or UN have been created to stop military conflicts. But what happens when a NATO member state declares war on another NATO member state?
From my yesterday's question about whether NATO can remove a member state from the organisation, I couldn't receive any positive answer on whether NATO can remove a member state . (Link - On what grounds can NATO remove a member state from the organisation?).
So in case of war between NATO member states, NATO has no provision to remove a member state and then trigger article 5? So what side would NATO member states would take in such a case.
