Realism is hard?
Look - what is BT?
In terms of global enterprises it is a splat, splot, spot, UK dependent thingy.
Invoke a principle of reciprocity and watch BT subsequently squirm, squash, die as Ruski, Merican, Canadian, ... telecoms come in and compete on even levels?
Dear BT: some swords are two edged, watch which ones you dare and/or care to use?
