Lithuania Moves to Lift Weapons Ban, Raising Nuclear Security Questions

Lithuania’s parliament voted Tuesday in favor of lifting a constitutional ban on the presence of weapons of mass destruction in the country, completing the first of two rounds required to adopt the amendment.

The proposed change could open the way for Lithuania to host nuclear weapons belonging to its allies in the future. The vote does not itself authorize a deployment, and the constitutional amendment still requires a second round of approval.

The move raises a security question that extends beyond the legal text: whether allowing such weapons would strengthen Lithuania’s protection against Russia or increase the risk of confrontation.

The potential deterrent value would rest on discouraging aggression by raising its possible costs. The competing concern is that hosting nuclear weapons could heighten tensions with Russia and expose Lithuania to greater danger in a crisis.

For now, lawmakers have advanced a change to what the constitution permits, rather than a decision to bring nuclear weapons into the country. Whether that opening would make Lithuania safer remains the central question.
