Part 3/9:

The first aspect of Zelensky's ultimatum concerns Ukraine's potential NATO membership. For Ukraine to become a NATO member, it would benefit from Article 5, which states that an attack on one member is an attack on all. This security guarantee would deter further Russian aggression. However, NATO's policy currently forbids admitting nations with ongoing territorial disputes. As a result, Ukraine's membership is complicated by its protracted conflict with Russia, which NATO does not want to amplify by entangling itself in existing disputes.
