Another one to remember - CIA's overthrow of the Allende governemnt in Chile. Interesting timing, as the date was also 9/11 - 1973, that is, not 2001.

The imperial ambitions of the USA's ruling oligarchs date from the very founding of the nation, and are unending (as are China's Russia's, etc.). There is always a new 'enemy' creagted to try and scare us with. Peace requires refusing to be scared by the oligarchs' fabricated 'enemies', and refusing to dehumanize others or be dehumanized ourselves.

See for example this recent talk by Eugen Drewermann: https://www.youtube.com/watch?v=7bxvAqiMl1I
