How much more troubled can the Jewish world be than the loss of three generations of Yidden to assimilation and having to rebuild after the Shoah in an America that wanted assimilation or an EY that forced secularization?
The Germany of WW1 was a civilized power. The reasons for the war were extremely complex. America at that time was a backwater and a social experiment that could have gone either way. Of course, it is all moot because Hashem determines what happens, but had I been a Jew in Europe I would have davened for a German victory.
