It is not that I want to promote the US of E. It is just that if we are bringing arguments against it, they have to be reasonable, and not laughable. The only two arguments I've ever heared from Britain were:
1. We never had a time in history in which the countries of continental Europe have been non-agressive and non-expansive (while Britain has). So there is no reason to assume this will change. Because it has always been like that, the EU can't and won't work! Fullstop!
2. And even if number 1 would be wrong, than it is because due to change after WWII the countries of continental Europe won't be mentally able to defend themselves anymore with weapons. If in the unlike situation it will happen that economy will flourish, another nation like Russia or India will immediatly attack the EU.
So with number 1 and 2 combined, the only rational solution are disarmed, political mute and economic strong countries under Anglican observation and military protection. Forever.
