Other thing is, that Ukraine had nuclear weapons, and when they gave it up, Russia and many other countries signed they will do all what is in their forces to keep whole Ukraine independant. I am sure all that signed that agreement are still alive, it happened 20 years ago.
Reality is you should not believe noone. Only reason why most world politicians say about Crimea as they do is since they are afraid same thing might happen to their country. But they will do nothing about it. They will just keep saying Russia broke rules. If Ukraine will want to get Crimea back will have to do it on their own and that will not happen. World will not do anything about it except say it was not good idea and they will say they are against it. But when will come to trade, no one will reduce it. All will just find ways to break embargos that will be set.
