1. "Western officials condemned Mr. Putin’s remarks as irresponsible"
2. "Ukraine’s Foreign Ministry condemned Mr. Putin’s remarks and claimed that basing Russian nuclear weapons in Belarus would violate the Treaty on the Nonproliferation of Nuclear Weapons, to which Moscow is a party."

When USA does it, it is not condemned?
