"But, awful as this atrocity was, native-born and homegrown terrorism is not the macro-threat to the continent.
"That threat comes from a burgeoning Muslim presence in a Europe that has never known mass immigration, its failure to assimilate, its growing alienation, and its sometime sympathy for Islamic militants and terrorists.
"Europe faces today an authentic and historic crisis.
"With her native-born populations aging, shrinking and dying, Europe’s nations have not discovered how to maintain their prosperity without immigrants. Yet the immigrants who have come – from the Caribbean, Africa, the Middle East, South Asia – have been slow to learn the language and have failed to attain the educational and occupational levels of Europeans. And the welfare states of Europe are breaking under the burden.[...]
"As for a climactic conflict between a once-Christian West and an Islamic world that is growing in numbers and advancing inexorably into Europe for the third time in 14 centuries, on this one, Breivik may be right."
I would posit that, since there have been NO Muslim terrorist attacks in Europe in recent years, the "crisis" Buchanan refers to probably doesn't fucking exist.
