Ukraine’s allies discuss concrete security guarantees at Paris summit
Allies discuss “NATO-style” guarantees and mechanisms to deter and respond to future Russian aggression.
Are we at war with Russia?
No.
Status last checked: (Europe/London)
Today’s context
As of the time shown above, there is no formal state of war between NATO members and Russia. NATO’s collective defence clause (Article 5) has not been invoked in relation to Russia, and NATO has not declared war on Russia. The situation remains volatile: Europe continues to deal with drones, sabotage, cyber activity, and diplomatic escalation linked to Russia’s war against Ukraine — but those developments do not automatically equal “war” between NATO and Russia.
We aim to give a plain-English answer up front, followed by concise background so you can interpret the day’s reporting without doom-scrolling. If a material change occurs (for example, a formal invocation of Article 5 or an official declaration of war by a NATO member), we will update this page and explain why.
What would change this answer?
- Formal actions: an official declaration of war by a state, or a NATO decision to act collectively under Article 5 after an armed attack on an Ally.
- Explicit, public statements by governments or NATO shifting posture from deterrence/support to direct conflict.
- Verified events recognised by Allies as armed attacks (not isolated incursions or non-attributed incidents).
Article 5 in plain English
Article 5 says an armed attack against one Ally is considered an attack against all. It is implemented by political decision: Allies weigh evidence and choose the collective response. Historically, Article 5 has been invoked only once (after the 9/11 attacks in 2001).
