Hey Gadge,
The British problem with food and resources almost sunk them twice, much like our problem with no industry came close in WW2. Perhaps we can (re)learn the WW2 lesson, when the Japs were heading south, and years of depending on Mother Britain for everything made in a factory, left us as naked as a centrefold, and we had to scramble to try and produce anything worthwhile ourselves. A lesson that was applied heavily in the aftermath of WW2, with a heavy industry program to make us self sufficient in all areas.
Ho ho...who am I kidding...
