Regarding the Previous Lubavitcher Rebbe’s prophecy [written in approx. 1943, in a publication called Keriah VeKudusah, explaining Tehillim 93].
[The Arizal says that our generation is a reincarnation of the generation that was in Egypt over 3,000 years ago. Also, the way in which the Geula will happen now will be similar to the way it happened in Egypt; as explained in the Hagaddah. Therefore, just as in Egypt, there were ten ways nature was changed in order to prove to the nations that G-d runs the world; so too now.]
There are two parts to the Prophecy:
1. Hashem wants the entire world (not just the Jews) to know that He runs the world; but simultaneously, He wants everyone to have free-choice.
How does He accomplish this, as well as the second part of the Prophecy [see below]?
Answer: Through flooding.
The flooding will reach to such an extent, that it will become obvious that these are not natural events.
2. The second part of the prophecy has not happened yet.
The Previous Rebbe says that a certain country will be either totally, or almost totally, inundated by flooding.
This will reach to such an extent that everyone will realize that this is a punishment from G-d; and the world’s political structure will change accordingly.
As explained in the talks from 1991-1992, as opposed to previous miracles that were mainly for Jews, the current changes will be visible to the entire world.
[As long as the wizards in Egypt could tell Pharaoh that they could duplicate Moshe's miracles, the Egyptians thought that Moshe was just a great wizard.]
So too now, as long as people can say that current events happen once every hundred years, or are due to natural causes; these events have not achieved their goal.
To say that these events happen once a century could be considered justified - if only one or two events were occurring - but when multiple events happen across the globe, how can they all be seen as happening once every one hundred years?
From the Previous Rebbe’s words it would seem that there is a land-locked country that will be entirely flooded.
It will not be near an ocean, so that we can’t say it is a tsunami; or in an earthquake or flooding zone, so that we can say it was nature.
And somehow the world will realize that G-d did it, in order to bring the Geula to the world.
