Most wars usa gets other countries to fight there wars, and wars usa mostly fights in they did not win.

Uk, Usa, got soviet countries to fight germany in ww2, but hollywood would tell you usa defeated germany by themselves.

Usa media did same in pacific to australia, when usa military took credit for battles aussies won against japan army in ww2.

Usa was never really attacked, so they can never say they came together, and have such moments, where they are proud of that they defeated some country trying to conquer them.

Usa military usually is starting the wars, as they want to take down there competition, or to put there bases everywhere, in terms of empire building.
