U.S. Interior Halts Five East Coast Offshore Wind Leases for 'National Security' Review

In 1948 President Truman shelved the St. Lawrence Seaway, citing submarine vulnerability; the project restarted in 1954 after design tweaks—a reminder that “national security” has long been a malleable veto on big infrastructure. Today’s freeze continues that tradition, reflecting a broader, century-long tug-of-war between federal administrations, courts and states over who steers America’s energy mix. Since coal’s 75 % share in 1950 gave way to oil, gas and now renewables, each transition has met partisan turbulence. Whether this pause permanently scares capital from the nascent U.S. offshore wind sector or merely delays first power, it underscores a systemic risk: when regulatory certainty hinges on electoral cycles, the multi-decade investments needed for decarbonization become wagers on political, not technological, durability—an instability future historians may judge as either a footnote or a decisive brake on the 21st-century energy pivot.
