Ukraine Takes Part in NATO War Games, Further Integrating Into Collective Defense Architecture

Ukrainian representatives participated in NATO war games simulating the alliance’s response to an attack.

According to a NATO press release, 1,500 soldiers and civilians from multiple European countries participated in the Loyal Dolos 2025 drills that were conducted at the beginning of the month. 

On Sunday, the General Staff of the Armed Forces posted on Facebook that Ukrainian officials participated in Loyal Dolos. “Ukraine is becoming part of the collective defense architecture of NATO. Ukrainian JATEC experts have, for the first time, joined the work of the mechanisms of Article 5 of the NATO Treaty on the training LOYAL DOLOS 2025,” the post explained. 

Senior National Representative of Ukraine in JATEC, director of Implementation of the programs of the Joint Center NATO-Ukraine Colonel Valery Vyshnivsky said, “The participation of Ukrainian JATEC experts in the LOYAL DOLOS 2025, which is one of the key elements of NATO’s preparation according to Article 5 of the North Atlantic Treaty, has strategic significance for us, as for the first time Ukrainian representatives have been involved in the work of the Alliance’s collective security mechanisms.” 

Kiev’s military ties to NATO countries are one of the primary reasons Russian President Vladimir Putin ordered the invasion of Ukraine in 2022. The Kremlin has demanded that Kiev agree to neutrality as a condition for ending the war. 

President Zelensky recently announced that Ukraine would agree to stop seeking formal membership in the North Atlantic Alliance if members of the bloc agreed to bilateral agreements with Kiev that are similar to NATO’s Article 5. Article 5 is considered the mutual defense pact in the NATO charter. 

That Ukraine is continuing its integration into NATO suggests that Kiev is still seeking to become an informal member of the bloc.
