I've been waiting for this for sometime. There was no reason for them to continue to be based there (let alone anywhere else in Europe) in such numbers. Poland will have to decide whether it is part of the EU or not. Sure, Poland will enjoy what in effect is a subsidy from the US, but at some point it will run out of goodwill for the US depending on how much political and economic arm twisting there is. At the end of the day, Poland is in Europe and the money comes through Brussels. The number of issues in which EU Member States can negotiate bi-laterally are shrinking rapidly (for example air agreements). Poland and the other CEECs will come up against this rock sooner rather than later. It will be much harder for the US to arm-twist EU Member States in future.
Still waiting for an agreement between Montenegro and the US for a naval base with a 75 year lease...
