Question

Do you think that Americans felt united after hearing this speech? Do you think they agreed with the President's decision to enter the war? Explain your answer.

Answer 1

I'm guessing you're referring to FDR's speech after the attack on Pearl Harbor?

If so, then yes, I would say Americans felt very united after hearing the speech. FDR used language that invoked very strong emotions. He spoke in a way that made Americans feel unified. By speaking about a common enemy like Japan, he made all Americans come together. It was almost like he was saying "here are the bad guys. Let's get together, and let's stop them."
So yes, it was very unifying. Do I think they agreed with him? Yes I do. He worded his speech in such a way that an American would have to be insane to disagree with him. His speech was infused with so much patriotism and nationalism that to not agree with FDR's decision would be seen as unpatriotic and unamerican.
