Surkov has made an anti-Ukrainian statement.
Former Russian President Vladimir Putin's aide Vladislav Surkov has said Ukraine "may be regained only by force."
That's according to his interview with the WarGonzo Telegram channel.
However, he did not specify what kind of force he was talking.
"Of course, by force. By force! The force is different, not only military. There is also the power of the special services, it is different. There is the so-called soft power, notorious term, but it also exists. There is the power of economic influence, political influence," he said.
