Could NATO Accept a new member who is at war?
Yes, but the probability of this happening in the next year or so is negligibly small. For that probability to be worth discussing here, Ukraine must win the war, and Russian Federation must undergo a process similar to that of Nazi Germany or Japan after WWII (ICC, deputinization, change of constitution, substantial change of the ruling elites, free and fair elections, etc). This takes time, probably 1-10 years even under the most optimistic scenarios currently discussed by professional historians and political analysts.
There are many reasons why NATO would not want to accept Ukraine as a new member state right now. The most prominent reason being the perception that this would increase the chance of a nuclear conflict. Now this may of course be true, but we may also be wrong here.
This is 100% true, are "we" are not wrong here. NATO Article 5 must be triggered automatically immediately after Ukraine joins (see REFERENCES below). Nuclear-armed NATO will be forced into immediately striking the nuclear-armed Russian Federation. Two nuclear powers will face each other face to face. Guess what follows, please select all that apply:
(a) Nothing, except maybe a pillow fight
(b) Intense condemnation
(c) A new round of negotiations, punctuated only by poisoning of the participants
(d) Stern speech by the President
(e) Nuclear war, using tactical and/or strategic nuclear and/or thermonuclear weapons
How do you eliminate option (e). Please use the space below this answer to comment and explain.
The principle of collective defence is at the very heart of NATO’s founding treaty. It remains a unique and enduring principle that binds its members together, committing them to protect each other and setting a spirit of solidarity within the Alliance.
- Collective defence means that an attack against one Ally is considered as an attack against all Allies.
- The principle of collective defence is enshrined in Article 5 of the Washington Treaty.
- NATO invoked Article 5 for the first time in its history after the 9/11 terrorist attacks against the United States.
- NATO has taken collective defence measures on several occasions, including in response to the situation in Syria and the Russian invasion of Ukraine.
- NATO has standing forces on active duty that contribute to the Alliance’s collective defence efforts on a permanent basis.
