A situation in which a difficult choice must be made between three mutually incompatible options or objectives; a three-way conflict where satisfying any two conditions makes the third impossible

Modern coinage modelled on 'dilemma', from Greek 'tri' (three) + 'lemma' (assumption/proposition). Entered policy discourse through economics (Mundell-Fleming impossible trinity) and strategic studies

Three-way Conflict Impossible Trinity Policy Trap Three-cornered Dilemma
Consensus Alignment Convergence
"India faces an energy security trilemma, simultaneously maintaining cheap Iranian crude imports, deepening Quad partnership with the USA, and preserving strategic autonomy, where any two objectives create tension with the third."

Powerful analytical term for GS-2 (IR, India's foreign policy, strategic autonomy) and GS-3 (Economy, monetary policy impossible trinity, energy security trade-offs). The Mundell-Fleming impossible trinity (fixed exchange rate + free capital flow + independent monetary policy, only two of three possible simultaneously) is a direct application in economics Mains. Use 'trilemma' in answers to signal analytical depth: 'The RBI faces a policy trilemma between rupee stability, growth support through rate cuts, and inflation control, no action satisfies all three objectives simultaneously.'
