All those in power at the time of WW2 have long passed on so to attach any responsibility to the present generations of Europeans is flawed. The European Coal, Iron and Steel Federation which morphed into the EU came about to ensure that never again would there be a major conflict in Europe. By breaking up the EU, faults and all, we are risking that peace which has lasted more or less in tact for over 70 years. The gap between WW1 and WW2 was just 21 years.
The Germans have become the leading European nation because they have worked hard and been governed well since WW2. The fact that Britain may have fallen behind is down to the British and our political system. Harking back to days of Empire when Britain was the world's strongest power does us no favours. Every British leader since WW2, except for Boris Johnson, has recognised that we need to be part of Europe. Theresa May, a European at heart, was handed a poison chalice by David Cameron, she gave up because in the end she realised Brexit could not be delivered.
The current government has messed up Covid-19 from the start for reasons well known. They had evidence from South Korea, Taiwan and the WHO which they chose not to follow at the cost of at least 20,000 lives. To them Brexit took priority over evrything including preparation for Covid-19 which they knew was coming.
That is why I and many of my fellow citizens feel ashmed of our Government hell bent on destroying a once great nation for reasons best known to themselves.
Few if any WW2 veterans are Brexiteers because they remember just how awful war was. I was born just after D-Day, though I do not remember much before 1950 I do remember rationing, bomb sites in Liverpool and other after effects of WW2 well enough not to risk a repeat.
