The president of Poland, Andrzej Duda, has repeated his call for the US to base nuclear weapons on Polish soil. In the presidential palace in Warsaw, he told me that it would make Poland stronger and safer, as it faces Russia. Viewed from Poland, President Putin's Russia is a clear and a present danger.

Poland's President Duda called on the U.S. to deploy nuclear weapons to his nation as a deterrent to any possible attack by Russia.
