Having been employed in the defence industry for nigh on half a century I do feel that it would be better is we didn't flog our kit to every man with a buck, or who wants a buck. If they do go else where we may hope that our kit is better.
Indonesian air defence had British Decca Radar
Argentina had British Type 42 and Canberra.
Iraq had British C2C systems.
Didn't the Taliban have Blowpipe?
Not to mention the French.
One marginal advantage is that we know the capabilities, or failings, of the kit.
Same deal with the training systems. We train 'em, we fight 'em.
