Small Places, Global Consequences
Block the Taiwan Strait and the semiconductor industry collapses. Close Hormuz and oil hits $200. Shut the Suez and Europe's supply chain seizes up. The world's most consequential geography fits on a kitchen table. This track connects the physical chokepoints — Hormuz, Bab el-Mandeb, Suez, Bosphorus — to the political ones: the UN Security Council and the semiconductor fabs. Narrow places, outsized leverage.
Eight places. Close any one of them and something breaks that can’t be fixed quickly. Knowing which eight — and who controls the approaches — is the closest thing to a cheat sheet that global strategy offers.

Chokepoints 13 minTaiwan Strait90% of advanced semiconductors are made on one side of this 130-km passage. A Chinese assault here would trigger the gravest global crisis since 1945.

Chokepoints 15 minStrait of HormuzOne-fifth of global oil—$1.2 billion per day—transits a 39-km gap where Iran's coastal missiles can hold the world economy at ransom.

Chokepoints 18 minBab el-MandebHouthi attacks proved this 26-km gap between Yemen and Djibouti can reroute global shipping—disrupting 10% of seaborne trade overnight.

Chokepoints 19 minSuez CanalEgypt's 193-km shortcut carries 12-15% of global trade. When blockages or wars shut it—as history repeatedly shows—the world economy convulses.
