How would we know the scale of time for the ikvesa d’mishicha? People can say it is, but there’s no way to truly know. The time of Mashiach’s arrival is hidden. Rashi states that Yaakov Avinu wanted to tell the shevatim when Mashiach would arrive, and Hashem took away his ruach hakodesh. Do you think Hashem would allow us to know now the time of Mashiach’s arrival?
At the end of the day, we just need to prepare for the arrival of Mashiach every day – achake lo b’chol yom sheyavo. Could the tragedies be ikvisa d’mishicha? Sure, they could. But Rabbonim said at the time of tach tat that Mashiach was coming. It was said at the Holocaust. It was said after the 9/11 attacks. Who knows? Only Hashem, and He’s not telling us! All we could do it prepare ourselves, and pray for Mashiach to come!
