In A Seicha the Rebbe says in short:
Even though it looks like it is going to be bad for the Jews and Israel, because the nations want to conquer the world, and in particular Jerusalem; nevertheless, all their plans will fail.
Therefore, Jews should not be occupied with world events, because Hashem will take care of it, it is already predestined what will happen.
Jews should rather be concerned with the things that they can control, being the education of their children.
___________
From this we see, that the Rebbe’s message is, not to be afraid, to trust in Hashem and realize, that everything that is happening in the world, is all a process that leads to the revelation of Moshiach.
And by the Jews passing this test, they help to bring Moshiach.
Don’t worry, be happy!
