I'm not pro Brexit, but ultimately if the decision is, not in the EU, then you will need a domestic farming policy, a fishing policy, a migration policy etc. We need to have our own foreign policy at the WTO etc, you need to decide what compromises can be made with your nearest neighbours for trade and investment and what commonality you have. Does it make it a better decision, no, but does a government have an obligation to manage the consequences of leaving then yes I would say it must. That is making it work.
There are a million decisions to be made. The consequences of the decision to leave are a bit more obvious. There is corruption. But this doesn't mean you can't do anything or have a different government with different priorities.
Close watchers of the EU and UK should keep looking for deals like the below. They will not be the only ones.
Both sides would be better off taking the emotional stuff out of it. That really is expensive
