Discuss the various constraints on American hegemony today. Which of these are likely to become more prominent in the future? (2023, 15 Marks)

Hegemony, in the Gramscian sense Robert W. Cox brought into IR (1981–83), is leadership resting on consent as well as coercion, so it can erode while material preponderance survives. The United States still spent $954 billion on its military in 2025, a third of the world total (SIPRI), and the dollar held about 57% of allocated reserves in early 2026 (IMF). What is constrained is its capacity to turn capability into accepted outcomes.

External constraints

  • China: a larger economy at purchasing-power parity, frontier rivalry in chips and AI, anti-access forces in the western Pacific, parallel institutions (AIIB, Belt and Road) and leverage shown by its 2025 rare-earth export curbs. Washington now manages rather than contains it (Donald Trump’s Beijing state visit, May 2026).
  • Russian revisionism: no ceasefire in Ukraine; New START lapsed on 5 February 2026 with no successor.
  • Middle-power hedging: India, Turkey, Brazil and the Gulf states practise multi-alignment; the BRICS New Delhi Declaration (September 2026) criticised unilateral tariffs and sanctions.
  • Limits of force: the US–Israeli war on Iran (from February 2026) brought Hormuz restrictions and a truce that broke down in July.

Internal constraints

  • Imperial overstretch (Paul Kennedy, The Rise and Fall of the Great Powers, 1987): Afghanistan and Iraq left lasting war fatigue.
  • Fiscal strain: federal net interest passed $1 trillion for the first time in fiscal 2025, and Moody’s withdrew the last AAA rating in May 2025.
  • The dollar’s double edge: the Triffin dilemma (Robert Triffin, 1960) ties reserve status to external deficits and a hollowed industrial base, while heavy use of sanctions spurs local-currency settlement.
  • Polarisation and unilateralism: America First tariffs hit partners (50% on India from August 2025, cut to 18% in February 2026); the Supreme Court struck down the emergency-powers tariffs (February 2026); and a January 2026 memorandum withdrew the US from 66 international bodies, draining Joseph S. Nye’s soft power.

Which will grow

ConstraintTrajectoryWhy
Domestic politics and debtRising, bindingCommitments reinterpreted every four years; interest crowds out defence and research
ChinaRisingCompounds with its technology base and supply-chain leverage
Middle-power hedgingRisingEach suitor raises the price of alignment
RussiaStableConventionally weakened, still disruptive
InstitutionsStableThey price unilateralism but bind only a hegemon that wants legitimacy (G. John Ikenberry’s strategic restraint)

The counterweight: Stephen G. Brooks and William C. Wohlforth (America Abroad, 2016) show that military reach, the dollar and frontier technology have no peer; the US share of world output (about 26% in 2024) is roughly that of 1990. Amitav Acharya (The End of American World Order, 2014) reads the trend as a multiplex order rather than a successor hegemon.

Conclusion

American hegemony is eroding without a replacement: Shivshankar Menon describes a world economically multipolar, politically confused and militarily unipolar. The constraints set to grow most are self-imposed, so the decline is of willingness and legitimacy more than capacity. For India this widens strategic autonomy but makes American guarantees less bankable.
