Polish Deputy Prime Minister Radek Sikorski warns Russia could launch a "false flag operation"

Polish Deputy Prime Minister Radek Sikorski said Russia could launch a "false flag operation" to try and justify an attack on a U.S. ally. "I wouldn't exclude the Russians doing some kind of false flag operation against Russian territory in order to have a pretext for hitting one of the NATO countries," Sikorski told CBS News' Aidan Stretch.
