What will NATO do if Putin really attacks one of its members in Europe? "That city is the alliance's weak spot"

What will NATO do if Putin really attacks one of its members in Europe? “That city is the alliance’s weak spot” Russian propaganda about annexing the Estonian border town of Narva has raised fears of invasion, prompting discussions on NATO’s potential response. While NATO has defense plans for the Baltic states and troops stationed in Estonia, Narva’s Russian-speaking population and proximity to Russia make it a strategic weak point. Military experts suggest direct NATO troop presence in Narva could deter Russia, but the alliance has not yet implemented such measures, especially with Russia engaged in Ukraine.

• Russian propaganda regarding the potential annexation of Narva is causing fear in Estonia, a NATO member.
• Estonian intelligence views the propaganda as a potential sign of Russian invasion preparations.
• NATO has defense plans for the Baltic states, considering them a joint operational zone.
• Multinational NATO battle groups are stationed in Estonia as a first line of defense.
• Narva, a border city with a predominantly Russian-speaking population, is considered a weak point due to its location.
• A direct NATO troop presence in Narva could increase deterrence, but this is not yet implemented.
• The current campaign is viewed as hybrid warfare, with immediate military threat unlikely as long as Russia does not publicly claim the need to ‘protect’ Russians in Estonia.
• Russia’s ongoing involvement in the war against Ukraine is another reason against an immediate threat.
