Right, and Puerto Rico (which became a territory rather than a protectorate). Most people forget about those. We also established some governance over regions captured during WWII and other conflicts, however temporary they may have been. But most of the &quot;capturing territory&quot; phase ended for the US prior to WWI, after that point control was established via less overt mechanisms (that is, no <i>direct</i> governorship, but we still had the military and economic means to direct them).
