1) Saves our lives in Europe, by having access to better training and force multipliers.
2) Seeps into the economies of every country in the union through research spending.
Defence is unambiguously a good thing, it becomes a problem if you put an expansionist cunthead at the helm of it.
I would think educating people properly is good, I also think the swizz model is good in sense of everyone learns to handle a gun and can have it at home (as long as high security standards are set and its taken very serious).
It could be used as a tool to strengthen societies responsibility, communication and combined with what the THW is doing (technical help org).
But my statment is still true:
We do not have to catch up. We are absolutly capable of defending ourselfs against the current biggest threat which is Russia.
We're undergoing a lot of propaganda about how effective Ukraine is against Russia, but that's despite most European countries practically immolating their own stockpiles of defence capability, and they're doing so somewhat unoformily (while Russia does everything they can to weaken the European homogeneity; see their funding into brexit and anti-EU seniment spreading bot farms on social media).
It's definitely not a given that we can stand up to Russia with our current capability, and it's also the case that we'd be throwing human capital at the problem because we failed to adequately invest.
I spoke to one person from Ukraine who was enlisted, he mentioned he was waiting for something from the UK, I asked how long does it normally take.. he told me that he doesn't measure time in weeks, but how many of his friends he he will lose.
.. that hit me hard, and it made me consider who incredibly naive and coddled I was to believe that investing in military or weapons things is a "right wing" or "bad" thing.
War always seems so far away until it's on your door.
My statement still stands, we do not need to increase defence spending to beat russia.
You said something different though: "We need to increase defence spending to have as little as human risk as possible".
I wouldn't call it naive, more optimistic. And even before Ukraine, we do have military. EU has high tec military.
Even before Ukraine, the EU spend more in military than Russia.
And regarding resources for Ukraine: We do fight a proxy war. We are not fighting Russia directly. This means some people don't want to spend money and resources on this, we are nog aligned across europe and it is always very unclear how and how much we help. This would look differently if russia would declare war against the EU.
Nominal spend is the wrong yardstick when one side builds at home for a fraction of the cost; Russian labour, steel and energy are far cheaper at the point of use, which is why PPP estimates put their real military output roughly level with the whole of Europe combined.
And spend isn't the binding constraint anyway: it's production. A budget line is not a full magazine, and we've spent years throwing our stockpiles into Ukraine while letting our shell and propellant lines wither instead of refilling them.
"We don't need to catch up" assumes the money on the page is already steel in the field. It isn't.
Russia has power because of their nuclear arsenal which is unclear how well it is maintained.
But no we can fill up and build faster and better than russia.
And the war against ukraine is hurting russia now for over 1000 days. Russia even has to go so far to reduce mobile and internet. This alone hurts Russia as a whole.
