The prof thinks:
(1) Americans are stupid.
(2) If we tell better lies we can fool them.
(3) We need to work harder on crafting better lies.

Yeah. They view Americans as dumb and slow-witted, but retaining a slight cunning. ‘The morons figured out lie A after 2 election cycles? No problem! Lets move on to lie B!’
