In my prior post, The Sprouting of Moshiach, I mentioned the end of Galus, which is rapidly approaching. I also mentioned that the year 5708 is a starting point, and there is symmetry between the birth of Avraham and Churban Bayit Sheini on one hand, and Churban Bayit Sheini and the founding of the State of Israel on the other.
Talmud Yerushalmi Masechet Brachot 2:4 brings a Midrash that on the day that the 2nd Beit HaMikdash was destroyed, Moshiach was born (it gives his name as Menachem ben Chizkiyah). This of course is not meant to be taken literally (we are not expecting a 1900 year old man to be proclaimed as Moshiach). Perhaps this is a hint to what I have written. Every 1880 years, Moshiach is born.
Of all that I wrote, only 1 item calls for immediate physical action from a majority of world Jewry: Aliyah. I stated that the year after the 63rd Yom HaAtzmaut would be a last chance to get out of Galus at our own volition. Let's take a look for parallels with 1879 years prior (i.e. 1880 years prior, but after this cutoff year). What we see is the beginning of the doomed Bar Kokhba Rebellion. The revolt ended such that the culmination of the failure is one of the things we mourn on Tishah B'Av.
Esav pursued Yaakov, and that was the end of Jewish autonomy for about 1800 years. It was a time of danger in the land of Esav, which unfortunately (for other reasons) at that time included Eretz Yisrael.
Such is not the case today. Esav's influence inside Eretz Yisrael is not nearly on the same level as it was. Moshiach ben Yosef of yesteryear was unable to act, only suffer. The chains of Galus were still too much to shake off. That is not the situation today. We are relatively safe from Esav's direct control here, and in about another year, Esav's influence will begin to decrease.
We live in the last generation of the Footsteps of Moshiach, there are no more do-overs. There is simply no space left on the 6000-year Calendar of Jewish history to account for further chances.
