Jaw-droppingly crazy proposals from immigration fanatics are nothing new, certainly not in the Wall Street Journal, but this piece by Gunnar Heinsohn in yesterday’s issue sets a record.

Mr. Heinsohn points out, as I have done myself, that the demographic vitality and economic hopelessness of Palestinian Arabs are sustained by the UNRWA welfare state. So:

Gazan teenagers have no future other than war. One rocket master killed is immediately replaced by three young men for whom a martyr’s death is no less honorable than victory.

What’s the solution? Why, we should open our arms — which is to say, our borders — to these angry, deprived young men:

If the West prefers calm around Gaza even before 2025, it may consider offering immigration to those young Palestinians only born because of the West’s well-meant but cruelly misguided aid. In the decades to come, North America and Europe will have to take in tens of millions of immigrants anyway to slow the aging of their populations. If, say, 200,000 of them are taken from the 360,000 boys coming of age in Gaza in the next 15 years, that would be a negligible move for the big democracies but a quantum leap for peace in the Near East.

What a great idea! The Middle East is seething with unemployable young men yearning for a martyr’s death? No problem — we’ll take ‘em! What could possibly go wrong?
