"The addition of Russian troops on the border, risk occupation"

Secretary of Defense Chuck Hagel said he was concerned that Moscow may be preparing an attack on Ukraine, after the recent military operations in the border. NATO has said in recent days about 20 thousand Russian troops are amassed on the border with Ukraine. Hagel said he agrees with the Foreign Minister of Poland, who said Wednesday that the increase of Russian forces near the border with Ukraine has increased the risk of a possible invasion. "I think it's a reality and absolutely, the possibility of interference exists," said Hagel, who was on a visit to Stuttgart, where he met with leaders of American troops in Europe. American officials have previously expressed concern that more than the numbers are the skills of Russian forces, which stressed Tuesday Pentagon spokesman Admiral John Kirby.
