Modi is not God.
He cannot operate in a vaccuum. There are constraints imposed by economy, strategy and diplomacy.
He can change all these factors ofcourse. But that takes time. For example, the changes he is bringing in economic sector of India are massive. A structural overhaul is happening. It will take atleast 5 years to bear fruit.
He is firmly putting India on the growth of 9% + growth rate. But that will kick in after a lag period of atleast 3-4 years.
So after a decade, that is 2025, India will be in a position to reap strategic benefits of what is happening now. We are today stuck with what the Congress did or did not do for the decade that it ruled.
This extends to military reforms, acquisitions, refurbishing the RAW, etc, etc.
It will all take time to bear fruit.
His real test will be if he gets elected in 2019.
