Well, the US forces actually attempted not to rig them.

No need to, the locals can do everything necessary. The US forces just provided the money and prevented the "undesirables" from playing.

Whichever laws you invoked when you said implied that "old-style colonialism won't work in our time" is a reasonable hypothesis.

I did not invoke any laws of nature. I think that in the current social, political, informational, military, etc. global environment the old-style colonialism is highly unlikely to work. No laws of nature are involved in this assertion.
