<span>One reason that native-born americans felt more threatened by the "new" immigrants than they had by the "old" immigrants was that the "new" immigrants brought different cultures and languages. These Nativists believed they were the true “Native” Americans, despite being descended from immigrants.</span>
I think it's all of them except the first one, Germany was not occupied by the allies :)

The Native Americans helped the French. The English were stealing the Native American's land and the Native American's felt that wasn't fair so they put their efforts and trust in the French. That is why it was called the French and Indian War because the French and the the Indians were allies and they fought together.
