I don't know either, but I do believe that any country who throws out the Jewish citizens is headed downhill. In the case of Spain, the New World obviously helped Spain become a world power for many years, but they did finally head down hill once the plundering ran its course. (Germany may have been a far stronger power if they had not killed or driven out their Jewish population.)
But as far as revision of history to give the New World to the muslims. (Ha Ha Ha...)
The effects of "the first world war" (by which I am referring to the period between 1805 and 1815, often called "The Napoleonic Wars") had as much to do with Spain's downfall as the removal of both Jews and Moslems from Spain. When Spain was overrun by the French, and could not dislodge them without signifigant help from Britain, the sign of weakness displayed by Spain gave the go-ahead to its far-flung colonies that independence could, and more importantly should, be striven for. Since Spain could not protect itself, colonists and indegenes pondered, how could Spain protect them?
