Americans can’t put anything into global context because every thing they consume has been cherry picked to solidify their American exceptionalism programming. That’s why American leftists are just liberals in denial.
The US has an educational system of indoctrination that begins & continues all through K-12 schooling & beyond. Its the propaganda of empire & it is necessary for a permanent war/oppression machine to carry out this indoctrination in order to maintain its systems of control.
