Tell the Americans that money they spend on arms manufacturing is a lost cause and ought not be included in US GDP....add to that the cost of their Nukes and Nuke maintenance .and dont mention the shit that they have circulating around in space!
What economic multiplier has the US or Russian Nukes got? What economic multiplier will our $400 billion Nuke Subs have?. (War is war.....not a business that yields a return on funds employed ...I guess there are exceptions like Iraq where US/Western corporations arrived later for the booty)
IMO you are looking at Government expenditure as an investment that produces a dividend and that only takes up a fraction of Western Governments' budgets.
