Have you read the first article?

Quote by you:

who was it again who launched a war THEY KNEW would consume all of Europe’s ballistic missile interceptors?

From the first article:

Germany has donated about one-third of its Patriot systems to Ukraine,

Oh and also from the article:

Israel is a unique case in the region but faces similar constraints. Its indigenous missile defense capabilities—including Arrow 3, Arrow 2, and David’s Sling—give it options that other US partners in the region do not have.

In other words Israel can build missile interceptors.

And then you even quote the article:

If US intelligence assessments are right that Putin plans to “test NATO resolve” in the coming years, then the replenishment clock matters on both sides

In other words, being able to access more interceptors is a key thing for European NATO members. Israel can make more of those.

Oh and this is from the US, who stopped Patriot missile sales to Ukraine BEFORE the war against Iran for months, because Zelensky did not war a suit. I would not be surprised if US stockpiles do not matter in a war at all, because the US is unwilling to sell them to Europe. That obviously would make Israel an even more important option.
