At present, India and the US share an extensive and expanding cultural, strategic, military, and economic relationship which is in the phase of implementing "confidence building measures" (CBM) to overcome the legacy of "trust deficit" – brought about by adversarial US foreign policies and multiple instances of technology denial – which have plagued the relationship over several decades. Unrealistic expectations after the conclusion of the 2008 U.S.–India Civil Nuclear Agreement (which underestimated negative public opinion regarding the long-term viability of nuclear power generation and civil-society endorsement for contractual guarantees on safeguards and liability) has given way to pragmatic realism and refocus on areas of cooperation which enjoy favourable political and electoral consensus.
