They don't say that in their press releases. None of the popular media coverage talks about the weapons aspect, much less that it's primary. I challenge you to prove me wrong.

The general public is not stupid (but they are lazy), when the dust settles and people see that nif never resulted in anything but very tangential results useful for power, they're going to complain about the lack of transparency. Just as they are doing with the whole COVID masking debate. Scientists really dig their own graves sometimes.
