Poland is discussing with the U.S. the joint use of atomic weapons to counter the growing threat from Russia, President Andrzej Duda said, Bloomberg reported.

“The problem, first of all, is that we don’t have nuclear weapons,” Duda said in an interview with the Gazeta Polska newspaper published on Wednesday. “There is always a potential opportunity to participate in nuclear sharing.”

Nuclear sharing can include anything from providing escort or reconnaissance aircraft for a nuclear mission or providing dual-use aircraft for nuclear functions, to actually deploying nuclear weapons. According to the Center for Arms Control and Nonproliferation, allies such as Germany, Belgium, the Netherlands, Italy and Turkey are deploying U.S. nuclear weapons on their territory.

A senior diplomat in Warsaw said Duda's comments could potentially include any of these actions. He said it is in the security interests of Poland, the region and all of Europe to deploy the weapons.

In April, Poland's de facto leader Jaroslaw Kaczynski, who heads the ruling Law and Justice party, told German newspaper Welt am Sontag that Poland was open to the deployment of U.S. nuclear weapons.
