India's unusually tough stand on the arrest of its diplomat Devyani Khobragade has forced the US to initiate an "inter-agency review" to look into the lapses that happened in

the high-profile case that triggered an uproar in India and strained bilateral ties. The US departments involved in the review include the National Security Council of the White House, the

State Department and the Justice Department. "An inter-agency review is going on right now to look into the lapses that happened in the case," sources told PTI. In a tacit

acknowledgement of the fact that there was a "judgemental error" in handling this case, sources said the inter-agency team led by the State Department is "working 24x7"

Pentagon is busy reviewing its policy towards Asia Pacific region wherein India fits as a major player in its scheme of things and is eyeing to have a large pie in the modernisation

programme of the Indian armed forces, the last thing it would like to see is any strain in its ties with New Delhi, officials said. The strong Indian reaction came as a "shock and

disbelief" here, especially to those who have anything to do with the country's foreign policy, as they had never expected such a strong retaliatory measure from New Delhi. Top

officials of the Obama Administration - in particular those in the State Department, Department of Justice and White House - took it simply a matter of "enforcing" law of the land,

which was exploited by Sangeeta to immigrate to the US. Those who matter in the India-US relationships including the government and the lawmakers have now started murmuring that the

"pros and cons" of such an arrest was not given a serious thoughtful consideration before giving a go ahead. "We have taken a hit. We will have to face the consequences,"

an administration source told PTI. India has asserted that such an arrest was not only in violation of the Vienna Convention on diplomatic and consular immunity given that she was a member

of the Indian delegation to the UN, but also against the letter and spirit of the India-US relationship, which President Barack Obama has been trying hard for the last five years. Officials

here concede that given New Delhi's past track record, it was never conceived by the American foreign policy makers that India would react to the arrest of its diplomat the manner it

did after the December 12 incident. After all, there had been precedent of Indian envoys and top past and present officials being subject to humiliating and disrespectful treatment during

their US visits, mostly at the airports, and there was hardly any protest, they said. But as India said "enough is enough" and raced to withdraw privileges of American diplomats in

India, officials here have been "forced to rethink" over their "treatment" and "relationship" with India, which Obama has described as the defining partnership

of the 21st century. India's unusual tough stand is being seen here as a reflection of the emergence of a strong and powerful country, officials said even as they continue to defend

the decision taken by them to arrest Khobragade. The Indian assertiveness was visible in the first 100 hours of the arrival of new envoy S Jaishankar who has a pro-US image because of his

key role in the historic nuclear deal. In his initial meetings with officials of the Obama Administration, Jaishankar made it clear that the "stalemate" in the bilateral ties would

continue till Khobragade issue is resolved in a respectful manner and New Delhi is assured that its diplomats are treated in a manner in which they should be. This has come as a surprise to

the US. It is this assertiveness of Indian diplomats and political leaders that is forcing US officials to evolve a fresh policy with India that takes into consideration its sensitivities.

"This (India's reaction after the arrest of Khobragade) is something, we never expected," another official said.
