Polish President Andrzej Duda announced that his country is ready to host U.S. nuclear weapons on its territory. He added, "If our allies decide to deploy nuclear weapons on our territory to enhance the security of NATO's eastern flank, we are prepared for that. We are a member of NATO and we also have commitments in this regard, which means we are simply implementing a joint policy." According to him, this issue "has been a topic in recent Polish-American negotiations." Duda pointed out that Russia is rapidly enhancing its military capabilities in the Kaliningrad region, adding that "Moscow recently transferred its nuclear weapons to Belarus." For its part, the Kremlin ensured that Russia would take necessary measures to guarantee "its security" if Warsaw hosted nuclear weapons on its territory. Russian presidential spokesman Dmitry Peskov stated, "The military will definitely analyze the situation, and in any case, they will take all necessary countermeasures to ensure our security." The U.S. nuclear sharing program allows the United States to deploy its nuclear arms in NATO countries that do not possess them.
