In a creative stroke of genius Esser Agaroth askes what we all think of the fact that July 4, 1776 was also 17 Tammuz. Although I agree wholeheartedly with his call:
Make Aliya Now!
I can't really make a case for the declaration of Independence being one of the tragedies that befell the Jewish people over the millenia.
Sorry, if you're gonna make aliya, and you should, it better be for a more positive reason. The pull has to be greater than the push, so to speak.
