Don't be so ridiculous. How could the British and American pollies convince their citizens, immediately after the conclusion of a war that killed and wounded millions of their people, and devastated and impoverished Europe, convince their citizens to immediately start another war? And whilst the USA was till fighting a war against Imperialist Japan.
To make such a banal statement is evidence enough of your anti-Western, and vindictive anti American blinded mindset. Did you really go to school?
And why would any country or person even contemplate consider the remote possibility of teaming up with such a cruel and insanely mad figure as Hitler. A person who was so mad and obnoxious that he had no hesitation in gassing, and grossly mutilating, millions of Jews, and anyone else who did not fit into the 'perfect' Aryan view of the world, eg Gypsies and anyone with physical and mental defects.
