He will emerge between Syria and Iraq, and his emergence will become known when he is in Isfahan (Iran) at a place called Yahudea (Jewish neighborhoud of Isfahan, Iran)
Below is what Karl wrote in a letter:
“The Jewish people as a whole will become its own Messiah. It will attain world dominion by the dissolution of other races, by the abolition of frontiers, the annihilation of monarchy and by the establishment of a world republic in which the Jews will everywhere exercise the privilege of citizenship.
In this New World Order the children of Israel will furnish all the leaders without encountering opposition. The Governments of the different peoples forming the world republic will fall without difficulty into the hands of the Jews. It will then be possible for the Jewish rulers to abolish private property and everywhere to make use of the resources of the state. Thus will the promise of the Talmud be fulfilled, in which is said that when the Messianic time is come, the Jews will have all the property of the whole world in their hands.”
