In this cartoon, a group of anti-imperialists holds bottles of medicine labeled 'anti-expansion policy,' while Uncle Sam's pants have stripes representing territories like 'Texas,' 'Louisiana Purchase,' 'Alaska,' and 'Hawaii.' President McKinley, represented by a tailor, is measuring Uncle Sam. At the bottom, the text reads: 'declined with thanks.' The anti says, 'Here, take a dose of this anti-fat and get thin again!' Uncle Sam responds, 'No, sonny! I never did take any of that stuff, and I am too old to begin!' What inference can be made from this cartoon?
a) The US government was willing to end its imperialist policies.
b) Some Americans were opposed to imperialism.
