In order to stay in the war against Germany 1939-41 and then to go on and make a major contribution to victory alongside the USA the UK had to produce huge quantities of industrial and agricultural product in these islands.
Peak production of aircraft was over 25,000 in a year, 250 major naval ships in a year, with millions of tonnes of new merchant ships. UK yards built 58 aircraft carriers during the war. There were big technical breakthroughs including radar, jet engines, a wooden warplane, bouncing bombs, and mulberry harbours.
The country got by with rationing of food combined with a dig for victory policy and the women’s land army.
Today a government who says we need to mend our defences delights in driving farmers out of business and in subsidising other uses for land than food growing. It runs down our industries, driving orders abroad by insisting on high energy prices and carbon taxes.
Where we had more than 50 aircraft carriers today we have just two, albeit much bigger and more sophisticated than many of the WW2 models. Where we could make 25,000 aircraft in a year today we would be hard pressed to build 25, and then only by relying on substantial imported components and raw materials. Our farmland has contracted as we become ever more dependent on imported food.
Before promising to deploy troops we do not have and to buy weapons we need the UK government needs to change its energy , business and industrial policies so we can make much for ourselves. It needs to actively back and promote self sufficiency in energy and temperate foodstuffs.
