MBD vs. Yishmael & MBY vs. Edom (part 2)

Here are a few more questions that I've been wondering about lately.

Why did Hashem decide that in 1948 we would lose the old city of Jerusalem and access to the Har Habayis? Why did we have to experience such an unbelievable miracle in 1967 with the re-unification? Why couldn't we just get it all at once?

There is a famous story quoted by the sefer Lev Eliyahu (Volume Shemos - Parshas Yisro p. 172) about the Chofetz Chaim. I'm now quoting directly from the sefer, which is a quote of the words of R' Elya Lopian (my own translation from the original Hebrew):

"I heard in London from the holy mouth of R. Elchanan Wasserman Zt'l, who said it in the name of the Chofetz Chaim ztvk'l, that our sages say that the war of Gog and Magog will be three times. At the time, it was after the first world war, and the Chofetz Chaim said that this war [that had just occurred] was the first Gog Umagog war. [He said that] in another approximately 25 years there would be another world war, which would make the first one look like nothing. Afterwards there will be a third Gog Umagog war - 'a time of trouble for Jacob, from which they will be saved.'"

I've always wondered - what is the idea of three wars? Obviously the first two have already passed. Is it possible that the first two had to do with MBY and therefore took place in the lands of Edom, affecting mostly Ashkenazic Jewry? Is it possible that we are witnessing currently the the third Gog Umagog war already - and it is connected to MBD and the world of Yishmael; hence the tremendous upheavals in the Arab world?

And how does Eretz Yisroel play into all this - it was spared from Hitler's wrath in WWII - and yet it seems to be center stage right now.

Other questions to ponder:

Why did the Ashkenazic world experience such religious devastation - being ravaged by the reform and conservative movements? Why did the Sephardic world not have so much infiltration - and largely remained either religious or traditional?

Why has Israel seemed to almost completely keep out the elements of the reform and conservative movements? And yet, why has Israel for the most part been ruled by Ashkenazic leaders who are irreligious?

Could there be a radical difference between what an MBY war of Gog Umagog looks like and an MBD war of Gog Umagog looks like? Is there any precedent for such a difference in previous examples of geulah/redemption? Are there any sources in the gemara for such a difference?
