The ongoing conflict between the US, Israel, and Iran offers significant lessons for global powers, particularly in understanding the dynamics of modern warfare. A potential ceasefire, while hoped for, is likely to result in an uneasy détente due to the entrenched positions of both Iran and Israel. This conflict, similar to the prolonged Ukraine-Russia war, illustrates that confrontations involving conventional weapons against a formidable opponent rarely conclude swiftly. Democracies, like the US, often incur higher costs in such conflicts, despite their military and economic advantages. For India, the ramifications of this conflict are particularly concerning, as it could lead to a reduction of over 1% in its growth rate for 2026-27 due to its heavy reliance on imported energy. This situation calls for urgent attention from Indian political leaders to enhance energy security through advancements in coal gasification, green hydrogen, renewables, and strategic reserves in oil and gas. Without addressing these vulnerabilities, India risks facing similar shocks in future crises.
