Granny I totally disagree.
The eu was a very hard sell during the campaign. It was all about project fear and there was no real solid positive argument given for the the eu.
We couldn't say we are safer in the eu because actually the 5 eyes etc is stronger, we give so much intelligence to them, smaller countries won't have same level of sophistication and any info passed onto them could be leaked anywhere. Eu isn't interested in keeping people safe.
Money! Well it was pushed during debates, thank goodness we didn't joined the euro, its disaster, destroying economies like Italy, counties are stuck and can't take measures that benefit them.
Socially... Again pretty much a disaster except for small amount of people, politically disaster, far right flourishing.
What are the positives..it's to large for parity and yet that is what it needs for success but that means closer union
There was very little good stuff to say so saying its our fault we left no. Its the eu fault for doing everything first without putting proper measures into place.
