When Indian diplomat Devyani Khobragade was arrested, handcuffed,& subjected to a strip search/CAVITY SEARCH in New York in 2013, New Delhi did not merely issue a strongly worded protest.
India hit back with reciprocal diplomatic measures:
-Removed security barricades outside the US Embassy in Delhi.
-Dismantled the illegal parking lot, the US embassy had erected for it's personnel.
-Withdrew special airport privileges and passes for US diplomats.
-Ordered US diplomatic personnel and families to surrender special ID cards.
-Reviewed tax, customs and other privileges enjoyed by American officials.
-Pressed Washington to withdraw a US diplomat linked to the dispute.
-Moved Devyani Khobragade to India's UN Mission, securing her full diplomatic immunity.
For once, India signalled that the dignity of an Indian official was not negotiable. The Obama administration protested strongly, but India simply brushed it aside.
Nations earn respect when they demonstrate that humiliating their citizens carries consequences. Btw, I forgot to mention the name of the Indian PM, then- It was MMS Ji.
