The biggest problem with UK leaving the EU

They aren't impotent. They were simply blindsided by Merkel last year. You can that as the snows clear, the fences are going up on the external border (excluding Greece that cannot be trusted).

Europe was always supposed to have a strong external frontier but Schengen expanded so fast since 2004 that countries (a) didn't want to spend money on an external border that would pretty soon become an internal border and (b) didn't have the capacity to fence build quickly enough.

Article 50 TEU is not a ransom clause, it is a divorcing clause. To rejoin the EU, we will have to apply for membership again where every member state will have to vote in favour.

If we wish to leave the EU right away, we can but if we haven't within 2 years, they will kick us out, unless both parties (UK + EU) agree to extend the period.

If we vote to leave, it doesn't mean we leave the EU straight away. We have to invoke article 50 of the Lisbon Treaty which starts a 2 year process where the EU gives us a deal. During the two years, we are still in the EU. We can delay invoking article 50, to give more time for us to make free trade deals with the EU and the rest of the world.

It took 10 years+ to negotiate FTA's with the USA and South Korea. You want to stay in for that long?

Yes, because eventually we will be outside of the EU.

No more EU arrest warrant, so all our criminals escape elsewhere, similar to the Costa del Crime in the 80s.
