An interesting view of the US and the wars it initiated in the 21th Century.

The US military defeats are products of a fatal flaw:  imperial planners cannot successfully replace indigenous people with colonial rulers and their local look-alikes.

Wars are not won by high tech weapons directed by absentee officials divorced from the people: they do not share their sense of peace and justice.

Exploited people informed by a spirit of communal resistance and self-sacrifice have demonstrated greater cohesion then rotating soldiers eager to return home and  mercenary soldiers with dollar signs in their eyes.
The lessons of lost wars have not been learned by those who preach the power of the military–industrial complex, which makes, sells and profits from weapons but lack the mass of humanity with lesser arms but with great conviction who have demonstrated their capacity to defeat imperial armies.
