In recent remarks at the Center for Strategic and International Studies, U.S. Secretary of State Rex Tillerson suggested that “India needs a reliable partner on the world stage…the United States is that partner.” However, India should respond with caution to friendly overtures from a government that views foreign policy primarily in transactional terms. Despite Tillerson’s repeated allusions to a “100 year” partnership, India should not be fooled into thinking that the U.S.-India honeymoon will last forever. In the context of the U.S.’s ambition to reassert its relevance in the Asia-Pacific, India’s growing military and economic power may soon fall afoul of Trump’s deal-making calculus. The administration’s transactional mindset is further complicated by the emotional volatility of Trump himself, who seems to use Twitter as his primary foreign policy tool. Even if Tillerson can teach Trump to respect diplomacy, the current U.S. foreign policy formulation will necessarily expire within either 4 or 8 years.
