Not only did they start the process of lifting this ban but they also announced they would build another military base if the U.S. would station troops there at no cost to the U.S. President Trump has already come out and said he would entertain this offer.
Another massive miscalculation by Russian media/elites. They thought they could continue to bully their neighbors, only for it to completely blow up in their faces. Ukraine was supposed to take days; now we are nearing 5 years with substantial Russian losses when it comes to taking the Fortress Belt, something they must take to conquer the Donbas.
