Russia has issued a chilling warning to NATO, stating that their nukes will be aimed at any NATO member that hosts nuclear weapons on their territory. This threat comes after Vladimir Putin approved a new nuclear doctrine less than two years ago, which lowered the threshold for nuclear use and reserved the right to use nuclear weapons in response to conventional weapons attacks that create a 'critical threat' to Russia's sovereignty and territorial integrity. The spokesperson for Putin, Dmitry Peskov, directly addressed Estonia, warning them that if nuclear weapons are deployed on their territory, Russia's nukes will be aimed at Estonia. This comes after Estonia's Minister of Foreign Affairs, Margus Tsahkna, stated that Estonia would be open to hosting a NATO ally's nuclear weapon on its territory if deemed necessary. The Arms Control Association reported that the updated nuclear doctrine was issued after the US authorized Ukraine to use long-range missiles supplied by the US to strike targets deeper into Russia. This development has heightened tensions between Russia and the West, and has sparked a debate about the potential consequences of nuclear proliferation and the role of NATO in European security.
