The way he's talking about Article 5 shows that he thinks that it's something that NATO can invoke to absorb Ukraine into the group, but that is not correct at all. Article 5 states, quote, the parties agree that an armed attack against one or more of them in Europe or North America shall be considered an attack against them all. And consequently, they agree that if such an armed attack occurs, each of them, in exercise of the right of individual or collective self-defense recognized by Article 51 of the Charter of the United Nations, will assist the party or parties so attacked by taking forthwith, individually, and in concert with other parties such action as it deems necessary, including the use of armed force to restore and maintain the security of the North Atlantic area. It's the rule. It's the rule that an attack on one member state is an attack on all member states, not a mechanism by which NATO can absorb countries into itself like it's the blob.
