Iran’s retaliation has exposed the limits of U.S. power: Gulf allies were hit despite hosting American bases, the Strait of Hormuz is shut, and global markets are recalibrating around a less reliable Washington. The war’s political and economic fallout accelerates a shift toward multipolarity — a moment many now compare to America’s Suez.
As of Friday, March 13, 2026, the strategic landscape of the Persian Gulf has fundamentally shifted. The “missile shield” that the Gulf Cooperation Council (GCC) spent billions to build over the last decade has been systematically targeted, exposing what analysts now call a “fragile sensor backbone.”
Iran’s unprecedented barrage on all six GCC states has shattered the Gulf’s belief that they could host U.S. bases, court Tehran diplomatically, and stay insulated from war. Missiles have crippled refineries, LNG exports, and data centers, while trust in both Washington and Tehran collapses — forcing Gulf rulers into a strategic reckoning they long tried to avoid.
Turkey is building a new Sunni‑majority alignment through rapid diplomacy with Saudi Arabia, Egypt, and Jordan. Arms deals, industrial cooperation, and coordinated statements on Gaza signal Ankara’s expanding influence. But rival ambitions, Gulf hedging, and Israel’s resistance to Turkish involvement in Gaza could limit how far this emerging coalition can solidify.
