The Evolving NATO-Ukraine Alliance

Since the Russian invasion of Ukraine in February 2022, the relationship between NATO and Ukraine has undergone a fundamental transformation.

This page tracks the institutional milestones, key statements, and the individual stances of member states that shape this unprecedented partnership.
