“We are now working together — Ukraine, the Europeans, the United States — to make sure that these security guarantees are of such a level that Vladimir Vladimirovich Putin sitting in Moscow will never try to attack Ukraine again,” Rutte said at a press conference.

According to the NATO chief, the security guarantees agreement will consist of two layers: strengthening Ukraine’s army and commitments from the U.S. and Europe aimed at deterring Russia in the event of future aggression.
