Security was a key concern on the agenda, especially in the wake of Obama's decision to scrap Bush-era missiled defense plans – including 10 interceptor missiles in Poland. The president told his hosts that the move did not put Poland’s security at risk and that NATO would guarantee the country’s security.
In earlier talks with Polish President Bronislaw Komorowski, Obama urged Poland to help Ukraine and Belarus with democratic reforms.
Obama criticized Belarus for "backsliding" and a 'total disregard for democratic values.'
Belarus President Alexander Lukashenko has intensified a crackdown on the opposition, jailing presidential candidates, and kicking out foreign media for stirring up "hysteria" over the country's economic crisis.
On Friday, US officials announced that F-16 fighters would be rotated to a Polish base for training purposes, in a further deepening of military ties.
Obama also said he and Tusk had discussed nuclear and gas energy cooperation. America’s Westinghouse Corp. is in the running to help build Poland’s first nuclear reactor by 2020.
