In keeping with Mahanian logic, US strategists like Theodore Roosevelt coveted sole possession of the archipelago. Rival sea powers Japan, Britain and Germany had voiced interest in acquiring some or all of the islands. Potential foes, it appeared, could obtain bases off the US west coast. This would not do. Washington must extend US rule to Hawaii to foreclose this latent naval threat.
However compelling Mahan’s brief for acquiring the islands, his appeals remained abstract until 1898. Anti-imperialist president Grover Cleveland scotched an annexation bid in 1893, before the Spanish-American War concentrated minds.
The US became a Pacific power overnight after wresting the Philippines from Spain. The US needed an island bridge to its new Pacific empire. Accordingly, Congress annexed Hawaii at the behest of president William McKinley.
Now, as then, Mahan’s logic is irresistible. Pearl Harbor will remain essential as long as the US remains an Asian sea power — a status the US has no intention of surrendering. But unless Washington manages its alliance with Tokyo wisely, Hawaii could become a bridge to nowhere.
