Poland has asked if it can host American nuclear weapons on its territory, amid growing fears that Vladimir Putin could use nuclear arms in Ukraine. The request from the Polish president, Andrzej Duda, is seen as “symbolic” said The Guardian, because moving nuclear warheads closer to Moscow would make them more “vulnerable and less militarily useful”. A White House spokesman played down the request saying: “We’re not aware of this issue being raised and would refer you to the government of Poland.” Duda’s remarks on basing nuclear weapons followed changes in the constitution of neighbouring Belarus that would allow Russian nuclear weapons to be based on its territory.
