Resources on deflection, desertion and political asylum?

We kinda lack info on how to defect here. I'm often thinking about that stuff... What would I do if the fascists ascent to power where I live? If it happens, it probably will be before anyone is ready to fight back. Fleeing looks sometimes necessary especially if you're unable to resist.

Does anyone know where to look to? Any historical or current examples of how people defect? What countries could be open to communist defectors from the West?
