US dreams of 'unipolar world' in nuclear deal pull-out: Russian foreign ministry

Washington's move to pull out of a landmark nuclear weapons treaty with Russia is motivated by a dream of a single global superpower, Russian state news agencies has cited Saturday a foreign ministry source as saying.

"The main motive is a dream of a unipolar world. Will it come true? No," a foreign ministry source told RIA Novosti state news agency.

The official said that Russia has "many times publicly denounced the US policy course towards dismantling the nuclear deal."
