Hi Swarf,
it is all about monery and power, the worlds richest nations supply weapons to the worlds poorest and it is one big "Merry-go-round", Britain intends to replace its nuclear submarine fleet with subs that cost billions, what about social housing, jobs for youths and policing the bank managers??.
Not to mention the cost of taking care of our lads and lasses with after care once they return home; and often in bits!!. (By that I mean mental and physical injuries)
