Like it matters whether or not a batch of 155mm shells passes through a Dutch warehouse or is delivered straight to Ukraine. The Dutch army hasn't had any significant stockpiles for decades, ordering stuff only as it was needed. Business as usual. The only stuff "in storage" in Feb. 2022 were the things that were up for sale, but nobody wanted to buy even at rock bottom prices.
Semantics for clickbait.
Pretty much the situation for every country.
Mothballed equipment in reserve destined for (dire) emergencies (pretty much everything that was sitting on our shelves), equipment about to be replaced (AMX10), stuff left out to rust (M113, Leo1, VABs, etc...) and things we "could get rid of without endangering our military capabilities".
Problem with that last category is it seems we adopted the Merkel "we will manage" approach, cutting large hoping it would do the trick and pay off. Which it didn't. And despite the claims of "Russia running out and about to lose 'any day now' ", we are 4 years in, with little hope for Ukraine to retake what they lost.
Now we have Ukraine mostly asking for more AD, and Poland taking PAC3 from their own active stocks.
So, it didn't pay off, and Europe has had to restart an industry with a huge inertia (to which we have to add the inherent inertia of Europe). Stocks haven't been replaced, shelves are not filled (and are far from getting there).
On the plus side, it kicked some sense into some people to make them realize the military, procurement, strategy (well, that's another topic), etc... had to go through profound and significant transformation.
So, at least, there is that.
