The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
Why would Germany want the US fighting against it, if they wanted their support against the British?
You do not specify if you are referring to World War I or World War II.
If you are talking about World War I, what happened was that the United States was a natural ally of the British for historic, political, and economic reasons.
Indeed, US President Woodrow Wilson had decided to remain neutral during the first stages of the war. He supported the allies with money loans, supplies, and weaponry.
However, everything changed when the US intercepted Zimmerman's telegram in which Germany asked México for his support in the war. That and the sinking of the Lusitania ship by the German navy made President Wilson ask Congress for a declaration of war against Germany.
No it is actually Tierra del Fuego because it translates to land of fire
It led to the revolutionary war
They feel sad(?). Because of the dead people who's body's are unknown?
Not willingly. Both superpowers had vested interests in the outcome of the war. Each country (Britain, France, Israel, The soviet Union and the United States) had different motives for doing what they did.
Britain and France had 2 motives: Oil and the Canal itself. Shipping was a huge consideration in the war.
The United States: mostly it was a matter of not letting the Arab nations get too upset. Oil again.
The Soviet Union: Oil and they were backing Egypt. The oil consideration was not for themselves. They (have/had) plenty of oil. They didn't want the balance of power shifting to the United States.
Israel: self preservation. That is always their motive.
