There are all sorts of reports, including the ones which point out that the oil and gas fields off the West coast of Scotland have remained unexplored because the British Ministry of Defense banned it because the nuclear submarines needed to get safely in and out of the Faslane naval base (Europe's biggest accumulation of nuclear weaponry, just 30 miles from Scotland's largest city).
My belief, based on the most recent independent reports, is that there is a great deal of oil and gas left ... but ... even if there was not a drop, it would still be better for the Scottish people to control their own destiny.
