Russia-US ties hard to mend, interests differ sharply

U.S. Army soldiers hold an American flag as they attend the official welcoming ceremony of the U.S. troops in Zagan, Poland, Saturday, Jan. 14, 2017. The ceremony comes 23 years after the last Soviet troops left Poland and also marks a new historic moment – the first time any Western forces are being deployed on a continuous basis to NATO’s eastern flank.
