Lithuania Moves to Lift Weapons Ban, Raising Questions Over Nuclear Deterrence

Lithuania’s parliament voted Tuesday in favour of lifting a constitutional ban on the presence of weapons of mass destruction in the country, taking the first step towards a change that could open the door to hosting allies’ nuclear weapons.

The vote was the first of two rounds required to adopt the amendment. It does not complete the constitutional change or amount to a decision to deploy nuclear weapons.

The proposal carries implications beyond its legal wording. Allowing allied nuclear weapons on Lithuanian territory could potentially add another layer of deterrence against Russia, making the consequences of any confrontation more severe.

But that possibility also raises a competing concern: whether hosting such weapons would increase Lithuania’s exposure to confrontation with Moscow rather than make it safer.

For now, parliament has advanced a legal option, not a deployment plan. The central question remains whether removing the ban would strengthen Lithuania’s protection or introduce greater risks into its security calculations.
