The Lithuanian parliament this week voted in favour of the first of two required ballots on the constitutional change. The second ballot is scheduled for 12 January next year. Lithuania, a NATO and EU member that shares a border with Russia's Kaliningrad exclave, has sought to remove the prohibition to strengthen its resilience amid growing security concerns.
President Donald Trump said on Monday that he would consider Lithuania's request for a permanent US military base, calling the country's leaders "great people." The Kremlin responded sharply. Spokesperson Dmitry Peskov said the developments "cannot be perceived as anything other than a step toward escalating tensions." He added that Moscow would be forced to "take all necessary measures to guarantee its own security."
