Georgia did indeed purchase NATO equipment. Also, Georgian soldiers were trained by American instructors, and very recently, the USA and Georgia held joint combat exercises, which, again, indirectly confirms the involvement of the USA in this problem and that it was a carefully planned operation.
Bow down and hear our cry,
Our earthly rulers falter,
Our people drift and die,
The walls of gold entomb us,
The swords of scorn divide,
Take not thy thunder from us,
Take away our pride.
G.K. Chesterton: English Hymnal
