Poland should emulate Norway, Iceland, Switzerland.
Emulate Norway? You mean - pay almost a billion Euro each year to the EU for the privilege of taking part in EU agreements, yet have no voice in the European institutions? That doesn't seem particularly sensible...
Emulate Switzerland? You mean - accept vast amounts of EU law, not have to pay - but still have to sign up to lots of treaties and agreements that makes them almost an EU member anyway? Don't forget what happened with Schengen and Dublin - failure to ratify both meant the door being slammed in their face and all the other treaties being cancelled.
Emulate Iceland? You mean - suffer huge financial instability without anyone to help you out - and have to resort to the Russians to help?
The longer Poland stays in EU, Poland will eventually lose it's sovereignty.
The EU doesn't work that way. Ultimately, countries can repeal the Act of Accession at any time they want - in fact, Lisbon has a formal exit mechanism for the first time.
Yay, we can go back to the era of 4-6 hour waits on the border, work permits needed, limits on imports and more!
As a remainder 20% of Poles voted against Poland accession to the EU.
4 out of every 5 voted for the EU, then.
So, US-Americans, Brits and a Serb discuss if Poland should leave the EU. Haha...
What's exceptionally funny is watching Americans discuss the EU - most of them haven't got a clue about how it actually works in practice.
