Well, its not clear quite how serious the UK is on joining the EU' Security Action for Europe (Safe) programme to organise European defence procurement...
Against a demand (request?) for a contribution of €6.7bn, the UK's opening offer is €75mn, suggesting that it is unlikely the two sides will reach an agreement on participation in SAFE by the end-of-month deadline.
Looks like the UK's Military Keynesianism*will* be a purely domestic affair, after all.
