NATO Allies Have Been Discussing Invoking Article 4: What to Know

Denmark on Sept. 26 confirmed there are no plans to invoke NATO’s Article 4, after drone incursions in its airspace earlier this week.

Foreign Minister Lars Lokke Rasmussen told reporters, “Article 4 has been activated nine times in NATO’s entire history, and twice recently in relation to Poland and Estonia, so we have no reason to do so.”
