These days though, I`ve talked to people in purchasing depts of British firms who long for the steel quality that they got from British Steel in Sheffield, the stuff now all comes from the far east and the variation from batch to batch, is unbelievable, and its highly doubtful if the material actually complies with the standard its sold under. Its far worse than was available here in the 80`s, but hey we saved 25% on our material costs ! so Yay !
The last time the steel mills were being shut down, Network Rail took a controlling interest in Scunthorpe steelworks, as apparently it's the only place they can reliably get the kind of rails they need in fairly large quantities every year. There are other steelworks that
can do it
, but not unreasonably they give first preference to their own national railways...
That's probably the real intent of the speech - "-or we could just..." is the unspoken part.
Supposedly, the kinds of numbers being discussed as needed are on the order of a total force of 500,000 people. Which is slightly more than a doubling of current forces personnel, and not far off what we had in 1989. A good recruitment drive, with adequate funding for pay and conditions, and confidence that recruits can enjoy a full military career, ought to do the trick.
Nobody is going to sign away the best years of their life to be underpaid, underappreciated, made to live in atrocious conditions whilst being shot at, and then be thrown aside with next to no notice because the Treasury needed to make in-year spending cuts.
Quite apart from anything else, there's no equipment for the UK to attempt mass mobilisation. The war reserve stocks were sold off decades ago, the warehouses they were kept in have been converted to industrial estates, and the factories that made them turned into housing developments! Yes, Ukraine has mass mobilised to an impressive degree - but arming the Ukranian army has required a good chunk of Western Europe and North America's industrial capability.
Attracting people will need large amounts of money and reforms to training and education which may not be available.
If the UK government really wants to improve its defence posture, it has the tools to make money available, and is only limited by the available human and industrial resources. If it doesn't want to, then the availability of funding and resources is irrelevant.
