NATO has sufficient safeguards to prevent accidental escalation. Article V indeed specifies that members commit themselves to assisting a fellow member when attacked, but this clause leaves enough room to remain on the safe side. First of all, the clause is only defensive, to ensure that NATO doesn’t become involved in a war of choice of any of its members, like the Gulf War. Secondly, article V allows members to choose their assistance in proportion to the actual security threat and according to their own means and goals, instead of the automatic triggers that led to World War I.
