Rome's Envoy to Saudi Arabia Converts to Islam
It is not just the U.S. that has the problem. Jews have been resisting for centuries but there seems to be a breakdown of resolve among the nations.
You are right about all too many European Christians converting to islam. Western churches are in trouble, except in Eastern Europe, parts of Asia, and in the global South (where they are fluorishing).
As for Judaism, it also is largely (with some exceptions) a spritual vaccuum in the US. And there are "Jews for Allah" (there is even a website by that name), including the islamist fifth columnist Stephen Schwartz/Suleyman Ahmad, who works to inflame relations between Roman Catholics and Orthodox Christians.
The main center of Christian resistance to islam is the Orthodox Church. And a significant number of Western Christians are converting to Orthodox Christianity, thus totally bypassing and opposing the siren call of the Wahhabi "missionaries".
