What are the four reasons that we did nothing to stop hitler

I believe 2 reasons are:

1.) The U.S didn't know what Hitler was doing until after the war

2.) The U.S wasn't sure how destructive he would be

i believe the answer to your question is b. pay your bills early

in mcculloch v. maryland (1819) the supreme court ruled that congress had implied powers under the necessary and proper clause of article i, section 8 of the constitution to create the second bank of the united states and that the state of maryland lacked the power to tax the bank.

gibbons v. ogden, (1824), was a landmark decision in which the supreme court of the united states held that the power to regulate interstate commerce, granted to congress by the commerce clause of the united states constitution, encompassed the power to regulate navigation.
