Ukraine

I mean, the article is from the Ukrainian military. I don't think that Ukraine cares much about whether-or-not the US has capacity to defend Taiwan. I think that the Ukrainian military cares a lot about whether there might be some additional, unknown delay in supply to Ukraine due to slowdowns in the production pipeline. Like, they had the EU promise artillery shells by a date, and they got delays and got half that much at the expected date. I'm pretty sure that they had plans predicated on getting that ammunition, had set burn rates, etc. Then there was the fight in Congress in the US over aid supply that caused a delay. I bet that they don't want more of those. If I were gonna guess, they're aiming to look ahead and say "what might become a delay" and then highlight that as soon as possible to people who might iron it out. The guy from the US says "there might be a month or two delay due to obtaining filler", they want that to be minimized and have a cap put on it.
