Israel cannot afford to stand against the entire world and be denounced as the aggressor.
For so long as the Jew has even one ally, he will be convinced - in his smallness of mind - that his salvation came from that ally. It is only when he is alone - against all of his own efforts and frantic attempts - that he will, through no choice, be compelled to turn to G-d.
This is my first experience working in a foreign movie, but the mechanics, I think, are pretty much the same all over; you still have to wait in the trailer.
