Bit of a contradiction here.
If CSD is a flat tyre, like you say it is, it is impossible to believe that US (thats the country you mean by international politics, dont you?) is not aware of it. If you say that the bogey of CSD is still helping you in negotiating with US, it means US is dumb, or they are just letting that perception permeate within Pakistani establishment; meaning US considers Pakistani leadership, that includes military leadership, as dumb. Not a very acceptable proposal, yes?
So, if CSD is working for you in your international politics, does that mean CSD may have some meat in it forcing your international partners (read US) to empathize with your concern?
Take a pick. You cant have it both ways.
