A. The dangerous and aggressive expansion of totalitarian nations

Explanation:

The rise of totalitarian nations and dictators such as Hitler, Mussolini, Franco, and Stalin, was a fundamental element in starting WW2. Totalitarian governments gave its leaders enough power to seek belligerent purposes without resistance from their populations.

This allowed them, specially in the case of Japan and Nazi Germany, to pursue aggressive invasions that eventually started the war.

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.
