COMCASA ordeal

Its been a while since India signed the COMCASA deal.  After contemplating the whole agreement, India finally signed the COMCASA during the last 2 + 2 meeting between USA's defense secretary, James Mattis and The secretary of the state, Michael Pompeo.
COMCASA or the Communication compatibility and security agreement is another version of CISMOA, specifically designed for India. COMCASA accord is a sign of growing intimate relations with the United States of America. It is one of the four major agreements that the US signs with its close allies. Though getting into this accord has not been too fruitful for India so far, this deal simply means that now India would be able to use advanced defense systems for communication, which is a creation of the states. It will work as a vehicle of contact between both militaries. Sure, it gives scope to India to buy high technology devices from US; however it also enslaves us in certain ways. Via this agreement the US military will have access to internal data of India, which can be a major setback, thus such a step taken by the Indian government aims at cajoling US at the cost of its security and safety, wherein they get a pawn in the form of India to control the south Asian region. Just a few days before signing COMCASA,  China's official newspaper named global times suggested India to not rush in into this deal. 
What India expected after signing COMCASA was a green flag for buying S400 missile defense system from Russia. This thing is illegal annexation of Crimea by Russia in the year 2014, which had resulted in economic sanctions on Russia by the West. Under these sanctions, an embargo on importing and exporting of military and dual used goods was also present. It seems that India have wistfully assumed that this accord would help them to buy the defense system from Russia without getting under the radar of the United States.
Even after becoming a close ally of USA, India failed to get any concessions. It is evident from the fact that the Oil crises going on in India are a result of sanctions placed on Iran by USA. The construction of chabahar port in Iran, which is a strategic point for trading with central Asia, is in midway due to the same reason. We could say that this diplomatic tie has not been a sugar deal for us and to say that this is the sanest decision taken by Indian government in a decade would be a clear cut lie too.
