That is because BJP used counter strategy. The 2G scam, coalgate scam, CWG scam, PAC agitation etc caused massive anger against UPA. CIA could not control the amount of pressure applied by RSS. The campaign done by RSS and BJP was overwhelming and nothing could overcome it. CIA indulges in deception based campaign but when important issues are raised, they will not have answers.And NGO funding wins election, why did they loose in 2014? Did CIA scale back funding after 2010 to elect Modi then? I would refrain from commenting on (common) sense, given every post in ref is devoid of it.
ISI of Pakistan was also involved in collaboration of USA along with the GCC petroleum producers.
