every country should attempt to be self sufficient as regards raw materials, the alternative is either going to war to get raw materials from someone else, or supporting undemocratic tyrannical regimes in the middle east., or importing cheaper fuel,and in the process destroying communities in the uk, creating ghettoes of unemployment, thatcher gave the miners who helped to save this country during the war a nice thankyou.

So, are you aying that Maggie was correct.
Buy coal cheaply elsewhere when we can, then, if there's another war, our reserves have not been depleted?
