They wrote a whole article about Europe's "atrophied and for so long neglected arms industry" yadda, yadda... and how Europe is thus struggle to even hit the 1 million shell per year mark aimed for.
And then at the very end they mention that the U.S.' own upscaled production even when reaching next year's production goals is only ~50k/month.
So the U.S. arms industry is completely broken and in even worse state or the whole theme of the article is just bullshit as usual? Pick one.
