Former CIA director: U.S. attempts to change Ukraine's border could lead to escalation.

"What worries me is that the current administration will not offer any peace plan," says former CIA director. "It will not be like that," he adds, referring to Washington's attempts to help Kiev return to its former borders. "I don't think it will work," says ex-CIA director, who is now in charge of Russia's relations with the rest of the world. "There is no way out," he says.
