While Article 5 of the NATO Treaty is mentioned often enough, Estonia also pays vital attention to Article 3, President Kersti Kaljulaid says. The president was speaking in the context of Exercise Spring Storm, the large-scale annual military event which started last Monday and whose progress she saw for herself during a visit Friday.
The president said: "Our article, Article 3 of the NATO Treaty, which first and foremost covers self-defense in one's own territory, is covered, while it is quite clear that our [NATO] allies have considered well how Article 5 might be applied here."
Article 5 concerns collective defense on the "attack on one member state is an attack on all" principle.
