According to the article, in his speech the foreign minister used a phrase which is equally insulting in both Polish and English. He said that Poland had abandoned its "murzyńskości" (loose translation is slave mentality, or servile attitude) in relations with the US.
Meanwhile, the Polish political opposition has been concerned over indications of tensions between Warsaw and Washington which put in doubt the aspiration for NATO military buildup in Central Europe.
"We will become a third-ranking country in NATO and the EU. We can see it already in international relations, including with our most important partner — the United States," Ryszard Petru, leader of the Modern opposition party, said in an interview with the Gazeta Wyborcza newspaper.

The US has criticized Poland for tightening government control over the Polish Constitutional Court and public media. Meanwhile, Warsaw hopes to strengthen US commitment to beef up NATO’s military presence in Central Europe.
