Bubbles,
So in Bubbles world Christians would have not only turned the other cheek, they would have turned their back on their fellows who were suffering under Hitler's evil, un-Christian new religion.  In Bubbles world, Hitler would have been allowed conquered the world and thrown not millions, but billions more people  into gas chambers and ovens.
.
In Bubbles world, he would have said 'we can't fight to make men free' and slavery would have kept the world   in chains.  
.
And finally, in Bubbles world, we would never have considered throwing off   England's tyrannical rule, as it wouldn't be right.  We never would have even become a nation, in Bubbles world. In Bubbles world Hitler would have won, slavery  would be the norm and America would never have ever existed!   How do you like that?
