The EU is kind of like the United States in the early days, a bunch of sovereign entities banding together for the common good. Now look at our current situation in relation to the sovereignty of the states. Every EU treay seems to bring the European countries closer to our current state.
One slightly good bit is that this gives individual parliaments a bit more say in what happens at the EU level, but I still see it as generally consolidating the power.
In 50 years we’ll have the EU just like the US, with what were individual countries not being much more than administrative districts within the EU.
So, it’s rather like Colonial America under the old Articles of Confederation...
And each nation is like Texas surrendering their sovreignity to join the USA.
