American imperialism is not the same as European imperialism. The Europeans wanted power, prestige and economic gain, while the US was in it for security. So, what will this look like for the Americans moving forward?
With current strategic holdings in places like Guam, the Northern Mariana Islands, and American Samoa, further expansion in Asia is more of a nice-to-have, than a need-to-do. Should the US want to make some moves, here are some of the places and considerations that would be involved.
Places like Sao Tomé and Principe, the Azores, and Canaries have some nice positioning for Africa, and Socotra could be valuable for Middle Eastern operations. Then there are some places that bring in another layer of risk, but offer some big incentives – Panama for the canal, Greenland for strategic positioning, or Iceland for importance in the North Atlantic. Cuba and Singapore are interesting, but more complicated. There’s some obvious history with Cuba that makes involvement spooky, but having a foothold would make national defense downright breezy. Tampering with the very solid security partnership with Singapore seems too risky, but having a firmer foot in Southeast Asia could be important in a deglobalizing world.
Yet to existing cooperative security arrangements, the US already enjoys the benefits of influence in almost all of these places without the need for boots on the ground, much less the grinding migraines that come from actual occupations. Expanding into new territories would require managing populations and infrastructure, which could weaken US strategic stability and risk turning allies hostile. What I’m getting at here is if it ain’t broke, don’t fix it.
