Now that the UPA has gone ahead with the deal, India no longer needs an External Affairs Minister once the deal is operationalised. This is due to the Hyde Act which required the US President to certify to Congress every year that India's foreign policy is congruent with that of the United States foreign policy. As they are deciding what our foreign policy should be, why have an external affairs ministry, indian embassies around the world, etc. We can post an IFS office to each and every American Embassy as he will report to the American Ambassador.
