OPINION: Jacinda Ardern's Christchurch Call to ban terrorist content being hosted online has finally got what it so desperately needed - the United States on-board.
And with that, the previously flagging Call gets a major shot of credibility.
Suddenly this initiative isn't just a bunch of do-gooder nations saying wonderfully important things about banning terrorist content. It now has the might of America to kickstart it.
America can make stuff happen and crucially, President Biden says countering racist and ethnically violent extremism is a compelling priority.
It's a welcome departure from former President Trump, who came up with a moronic and deluded excuse to stay out of it by saying he didn't want barriers put in the way of free speech.
Well, anyone recording a live video of themselves killing dozens of innocents at a Friday afternoon prayer session is not practising free speech - it's extremism, and their currency is pure evil.
It's a coup for Ardern - easily her biggest foreign affairs win.
She and French President Emmanuel Macron will host the second annual meeting virtually this weekend, and the US will be logged into the Zoom call. Could Biden make an appearance?
Whatever happens, it's the first real sign of warmth from the administration post-Trump.
Biden has seriously boosted this international initiative, which was struggling.
And looking wider, I think there's a good chance he'll get Ardern to the Oval Office at some stage this term - COVID willing.
And after a difficult relationship with Trump, Ardern will jump at the chance.
