Russia Issues Nuclear Warning to NATO Amidst Rising Tensions with Estonia

Moscow has escalated its rhetoric, threatening to target Estonia with nuclear weapons if NATO were to position nuclear capabilities within its territory. This warning comes as tensions rise in the Baltic region, fueled by concerns over potential Russian aggression and bolstered defense spending by NATO members.
