What will happen to the EU if anti-EU nationalists win a majority of the seats in the EU elections? EU strongholds (France and Germany) are losing ground. Italy, Hungary, Poland and others are become quite hostile to this expanded view of the EU. Spain and Greece are turning away.
This spring's elections will bring huge changes. It may not be the death of the current version of he EU - but, even if it survives, it will be weakened terribly.
Brexit is just fine. The UK will easily find trading partners to make up for anything the EU foolishly refuses to sell them. Whatever happens the EU member states will not be united and will not be able to organize a united front against the UK.
