Why can't we do it again? We are being inundated with calls from remoaners that we will be doomed if we leave the EU. Why? For centuries our little island nation has punched above it's weight, through sheer dogged determination. From my view, since we joined the EU we have been bogged down by pettifogging EU regulations that have prevented the innovation we were renowned for.
I admit that it could take a considerable time until the new generation in the UK learns that greatness can be theirs. Unfortunately my generation I suspect, will not live to see the greatness I saw in my early life.
Just go and do it.
