This film views the world as a place far away where we can sit back and let people at our door step do as they wish. If anything of WW2 has taught us anything it is a power left unchecked will grow into a greater conflict.
Solution? We had hopes to let they govern them self. didn't work. what does work.. well another note from ww2 the occupied people of France soon saw the Germans as their own people and some would wed.
You may ask why do I bring this up? Well both that and the cold war saw The united states funding/ creating a situation which ended in evicting the occupation.
Answer? Short of mass slaughter, capturing the hearts and minds of the populous and helping them understand we want what is best for them and will help them get there. This being not constantly in-fighting, not constantly switching sides and points, and not falling through on our word.. ie Cuba, Iraq. and so on and so forth.
But then again you don't have to take my word for it.
