The US purports to be against colonizing... except in the cases of Hawaii, the Philippines (and you might want to check out what Mark Twain had to say
about THAT little adventure - he was, imo, a truly great American), Puerto Rico, Guam, Diego Garcia and a handful of other tiny spots.
But actually, when you look at the history, you find, for example, that the main point of the Monroe doctrine was to announce to the rest of the world
that Central and South America was US PROPERTY - HANDS OFF. There has been a continual parade of interventions, invasions, and coups which have all
been designed to subjugate the South American states, the latest of which were Haiti in 2003 and Venezuela in 2002 - the latter, I'm ecstatic to
report, unsuccessful.
The Monroe doctrine was ignored by the US in any event: they were instrumental in the coup that brought the military cabal to power in Greece in the
sixties, and they interfered in Italian and French politics to try and destroy the Communist party in those countries. They also removed the Gough
Whitlam government in Australia in the mid-seventies.
As for Indonesia, it followed a remarkably consistent US pattern, as
this
link (the first one I came across, as it happens, but it works rather well) demonstrates.
As it was on the way to the printers, both the CIA and the United States State Department took action to block the publication of a book detailing
U.S. covert action and goverment involvement in the coup in Indonesia which resulted in the loss of up to one million lives (the victims
of the U.S. sponsored purge were leftists, not surprisingly). The documents have been reproduced on the George Washington University Archive site and
reveal that American involvement included passing the names of leftists to the Indonesian death squads (with the Ambassador at the time
suggesting that these steps were required since, on their own, the Indonesia military seemed to be to clueless to figure out who these people were
themselves.)
In one of the more interesting quotes from the article the embassy reports back to Washington at the time that "We frankly do not know whether the
real figure" of communists who have been killed "is closer to 100,000 or 1,000,000 but believe it wiser to err on the side of the lower estimates,
especially when questioned by the press." The comminiques also address the possibility of public disclosure of U.S. covert action and involvement in
the massacres by noting that "The chances of detection or subsequent revelation of our support in this instance are as minimal as any black bag
operation can be."
Against colonizing? Overtly, yes, covertly, no.
