Ossie, if you look at the
history of Germany, it's been a bunch of semi independent states since Roman times. It didn't start to become forged into a nation fully till 1871 and has only had it's current form since 1945. Most of Bavaria was Austrian and always had been so long as there was an Austria. Which explains a lot to me.
I've known a bit about Germany history but as I didn't bother with history at school (no memory for irrelevant facts as I saw them), I really hadn't studied it. However if you look at the post 1871 Germany and the post 1918 Germany, you can perhaps understand why people didn't quite jump into war at the threat of taking "back" Poland.
If they are trying to turn the UK into a federal state like Germany they are on a hiding to nothing. England has been England since, pretty much, the 10th century. It's been one country since 1066 and has had one administration since 1066. When you look at France and the Plantagenet empire, Italy and the fact that it has only been around in it's current form for less than 200 years, you can understand the EU mania for "federalism" and trying to use the regions to work against the centre.
However in the UK, this simply doesn't wash. People don't want it and people see no benefit in it. Which is why I think, in the end, it will fail. Unless, of course, people don't vote on it as an issue.
