I have a simple policy when it comes to predicting when Moshiach will come.
Don’t predict. When he gets here, HaShem will make it perfectly clear. Simply wait for him every day and quit trying to make cheshbonos… you’re only bound to be disappointed if you’re wrong.
While we’re at it, I have a personal pet theory as to who Moshiach will be:
Anyone who can get all of K’lal Yisroel to agree that he’s Moshiach has to be the real deal. If someone could get all Ashkenazim and Sephardim, Chassidim (for all different sects) and “Misnagdim,” Yeshivish, MO, Chareidi and DL to agree that he’s Moshiach, then he’s got to be it.
