I think that's less true than the media would have you believe.

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.

Its not propaganda when you can see it. We know what Putin showes in his Military parade and we know the stockpile of tanks they have and had due to satelite images.

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.
