If you walk into the room spouting that white tower zero sum game political science rubbish you'll be bent over a hooker on friday. You are not dealing with an academic or bureaucrat. 
You are dealing with a killer.  He eats you, spits you out then says he's taking your momma.

You are not dealing with a bimbo politician who can't spell economy and relies on his aides to tell him what zero bound is.

 You are dealing with a penultimate deal maker who will rip you apart then give you back Ottawa to make you feel better.

The Political science rubbish you just wrote will not do you well in this deal. It is a deal my friend not a negotiation. Your zero sum game foolishness doesn't work n the business world. 
He will take your kidneys leave you with a dick to pee with. Not much good.

You damn well better adjust your strategy or it you will walk out with nothing.
