a nation is shaped not by just one or two decisions, it is shaped by the decisions and choices made by every individual every moment.. It is just that we identify some consequences and try to corelate the same to the immediately precding cause. Anyway I am listing below the top 5 events which played a significant role in the shaping of this country's destiny ( post 1947 ) Gandhi's subtle Autocracy: He imposing his personal choice ( Nehru ) as the leader of congress and prime minister of this country ( against the more popular choice sardar vallabhai patel; similarly forcing India to be a homeland for muslims as well ( despite creation of a Muslim Pakistan ). Imagine we would have had no inter-religious conflict / riots at all. Ambedkar's revenge.: By giving a stamp of authority on caste based reservation , in one shot , India got divided along caste lines and some other real , critical issues like population control, accountability, responsibility, meritocracy, economic considerations got trivialised/relegated to the background; Top down approach coupled with excessive centralization destroying panchayati raj and federal nature of our nation. Linguistic reorganization of states which further divided this country and weakened it.. we are now first kannadigas,tamilians, marathis, bengalis, keralites, punjabis etc and then Indians No Review / Watchdog monitoring the efficiency of the judicial system resulting in stock piling of cases and unacceptable delays.
