The issues and benefits you list are not specific to either "side". It feels a bit like you picked and chose through rose-tinted glasses when, really, everything you listed may happen in either case and are more symptoms of the quality of leadership.

Europe undermines itself because they are constantly shooting themselves in the foot, starting from their own governments.
