Identify one argument against american imperialism. the united states had sufficient sources of raw materials so there was no need for imperialism social darwinism meant that since the united states was superior, it should weaker nations the us army was too small to be effective overseas imperialism goes against classic american principles and violated the constitution

The correct statement is the last one.

The US Constitution discusses how a good country should be run by "the consent of the governed." This is a concept that basically states that the US government should cater to the needs/wants of the citizens. In this case, imperialism would be seen as going against this idea. This is because imperialism involves taking over a country/territory and establishing systems that will benefit America. This meant that the people who were being taken over didn't necessarily want the US to be there anyways.
