A few years ago I was involved in doing business is what was then the Soviet Union. Part of a project called Conversion 90 which under Gorbachov was trying to convert military production into domestic. Sort of swords into ploughshares thing.
Over a bottle of Vodka or two we had a lengthy discussion with some guys from a place called Chelyabinsk which is/was one of the centres of the Russian nuclear arms industry. We talked about the cold war and our mutual perceptions of one another and it was alarming how similar we all were. We all wanted bascially the same things. Roof over head, food in belly, hotty in bed etc etc.
Anyway, we eventually started talking about the nuclear deterrant, and their response was very simple and it went a bit like this:-
1) We lost 20 – 45 million people in the last war (depending whose numbers you believe)
2) We have been invaded and had wars fought over our territory on numerous occasions
3) We are a communist command economy, what we spend on weapons doesn't get spent on civilian goods
4) Americas 2nd world War losses were less than 1/2 million
5) They have never been invaded.
6) Weapons production in America is big business and highly profitable
So who is deterring who???
Personally I couldn't fault their logic, and history does suggest that they pretty much bankrupted themselves keeping up with the Jones.
