Mutual Blackmail: Economic Treaty Organization Between Afghanistan, Pakistan and India
So what to do next? Much has already been said about the Indo-Pak rivalry and history, and how it affects the present conflict as well, but it is high time for a bold idea that takes it into account, and lays the basis for achieving US goals as well, based on the idea that "friendship is merely mutual blackmail elevated to a higher level". The US should create and fund an Economic Treaty Organization between Afghanistan, Pakistan and India that will create all the elements of mutual blackmail by tying together long term economic interests of all the parties involved, thus in time elevating it to the higher level of friendship, as already stated above. The return on investment of such a plan is going to be far higher than cleaning up the mess afterwards, and anything less would fail to the detriment of all. After having exhausted all other possibilities, it is high time the Americans did the right thing. Countless millions are counting on it.
