"It is not a part of American history that we're proud of,"...

IF the US was involved in slapping down Allende then I'd consider this a very proud moment in American history. Allende was in the process of turning Chile into a Marxist 'paradise' (i.e., 'hell-hole'). Good for General Pinochet - and 'whoever' helped him.
Just look at Chile today as compared to the rest of the basket-case countries in South America. Chile is the only country not treading in quicksand.

--an oft-ignored fact is that General Pinochet received a larger percentage of the vote when he lost and left office than Allende had obtained in winning--
