Should increase it. First line of defense against Radical Islam.
That's true as far as Israel is concerned but Europe and the US are on their own.
“Jews should rejoice at the fact that Christian Europe is losing its identity as a punishment for what it did to us for the hundreds of years were in exile there,” the rabbi explained as the ethical reason for favoring Muslims, quoting shocking descriptions from the Rishonim literature (written by leading rabbis who lived during the 11th to 15th centuries) about pogroms and mass murders committed by Christians against Jews.
Efrati ruled, therefore, that “even if we are in a major war with the region’s Arabs over the Land of Israel, Islam is still much better as a gentile culture than Christianity.”
He added, however, that Jews must pray that the Islamization of most of Europe will not harm the people of Israel.
“We will never forgive Europe’s Christians for slaughtering millions of our children, women and elderly… Not just in the recent Holocaust, but throughout the generations, in a consistent manner which characterizes all factions of hypocritical Christianity…
“A now, Europe is losing its identity in favor of another people and another religion, and there will be no remnants and survivors from the impurity of Christianity, which shed a lot of blood it won’t be able to atone for.”
