what happens if a nato member attacks another

If a NATO member attacks another NATO member, the response would depend on the specific circumstances and motivations behind the conflict. However, if a NATO ally is attacked, then all NATO allies are attacked, according to the principle of collective defense. This means that the member that was attacked could invoke Article 5, and the remaining NATO members would come to their defense. The attacker would have no support from NATO. The consequences for the attacking ally could depend on whether they are the aggressor or not. Since the Treaty itself doesn’t have explicit provisions on governing a war between NATO allies, the consequences for such actions are not perfectly clear. However, the Treaty gives guidelines which could provide a potential answer. Diplomatic efforts would likely be the first course of action, with other NATO members acting as mediators to facilitate dialogue and a peaceful resolution. The repercussions of NATO members attacking each other would be significant and far-reaching, seriously undermining the credibility and unity of the alliance, potentially leading to its fragmentation.
