Apart from the fairly crude attempt to make people feel unpatriotic for wanting a system that should hopefully make it harder for politicians to get away with starting wars, the central premise seems to be the idea that spending money on this process will somehow impede improvements in the Army's equipment.
Except that all of the evidence suggests that sheer incompetence at every level, especially in the bits of the government that currently handle military procurement, are the main things stopping such improvements - ridiculously complicated finance deals that end up costing billions more than they need to. £250 million is a drop in the ocean by these standards.
I'm currently not too keen on the reform guys either, since they are sending me WAY too many emails, but so far they haven't insulted my intelligence to this extent.
Looking forward to the referendum, or whatever they end up calling it.
Later: Looking at their web site doesn't make it very clear who is behind this, but the person named (William Norton) appears to be a solicitor associated with the Conservatives, if it's the same person. Not much of a surprise...
