The total of America's military bases in other people's countries in 2005, according to official sources, was 737.
....

These numbers, although staggeringly big, do not begin to cover all the actual bases we occupy globally. The 2005 Base Structure Report fails, for instance, to mention any garrisons in Kosovo (or Serbia, of which Kosovo is still officially a province) -- even though it is the site of the huge Camp Bondsteel built in 1999 and maintained ever since by the KBR corporation (formerly known as Kellogg Brown & Root), a subsidiary of the Halliburton Corporation of Houston.

Interestingly enough, the thirty-eight large and medium-sized American facilities spread around the globe in 2005 -- mostly air and naval bases for our bombers and fleets -- almost exactly equals Britain's thirty-six naval bases and army garrisons at its imperial zenith in 1898. The Roman Empire at its height in 117 AD required thirty-seven major bases to police its realm from Britannia to Egypt, from Hispania to Armenia.
