Western allies are preparing to offer Ukraine a series of security guarantees that will make the country “impregnable” from another Russian attack.

He noted that security guarantees for Ukraine will not be identical to the fifth article of NATO (an attack on one country of the alliance is considered an attack on all its members – ed.).
