The OPEC+ cartel has just delivered a massive snub to Western governments facing the worst energy crisis in half a century.

Look past the buzzwords accompanying Wednesday's cut in oil production — preemptive move, uncertain outlook — and it’s difficult to see the move as anything but an attack on a global economy that desperately needs the price of crude to remain subdued.

In all its history, OPEC — and its new incarnation, the OPEC+ alliance — has never curbed output so much, and so quickly. Triple-digit prices used to push the group into output-boost mode, not the reverse.
