The public at large disagree with your statement - the public do not want dying land forces 'in the national interest', so the RAF can have more money to spend on platforms which are incomplete.
And it is the public who largely decide which politicians get elected and hence what is in the national interest. Backed of course by the press who reflect the public mood that deaths of army chaps on the ground to keep Nimrod et all funded is not 'in the public interest'.
