There are a couple of people who've done videos on that aspect though I've not watched them but while it does reduce what would have been available in a total war situation much of the gear is stuff which was coming up on being cycled out, replaced or coming up on its use by date so NATO arsenals aren't being depleted to any significant degree. We do need to cut through some of the usual tape though when it comes to replacing stuff IMO so as not to be in a wrong footed position if there is an escalation - some of this stuff might take months and a lot of cost to produce in peace time but there is no reason for it to be that in a war time situation - there isn't a physical barrier which prevents some of these missiles from being put together in large numbers in days rather than months for instance.
Costs I can't see doing anything but spiral for a long time but it is a new reality we will have to embrace and find solutions for.
