By no less than Luc Montagnier himself. This looks like the nuclear letter by Einstein to Roosevelt. WSJ is one of the very few remaining solid objective outlets in the US.
Nor should one blindly trust a Nobel Prize winner.
cft (who, like us all, is not devoid of bias) linked to Wikipedia as support for the importance of this letter. I think it's only fair to examine that page to check if that support is appropriate.
During the COVID-19 pandemic, Montagnier was a promoter of the conspiracy theory that SARS-CoV-2, the causative virus, was deliberately created in, and thereafter escaped from a laboratory. Such a claim has been refuted by other virologists.
There's a ring of people here that gang up and downvote posts, waging political wars. Then they seek out and downvote others recent comments by the same user. dang has to look into this.
This looks like idea laundering.
