I absolutely sympathise with Ukraine and want them to win, but for now all the talk about Russia attacking Nato is just talk. Nato is a defensive alliance, nothing more. To preemptively attack Russia because we think they might attack us, is not what the alliance was set up to do.

For now all the talk about Russia attacking Nato is just talk

Its regime is already attacking NATO -- at least from what more or less officially amounts to NATO's perspective:

Russian acts of sabotage may lead to NATO invoking Article 5, says BND chief - https://news.ycombinator.com/item?id=42276160

Just not in any old school, "tanks across the Vistula" sense.

But in a modern 21st century sense.

Russia attacked Ukraine.

Ukraine had agreements from the West that we would defend them if Russia ever invaded. We are in violation of those agreements technically even with the level of support that was shown, which we provided as assurances for Ukraine surrendering its nuclear capability.

You're conflating attack and defense, framing the West funding of Ukraine's defense as an attack. You are downplaying the aggression that Putin has showed in multiple occasions in defiance of international law.

It's hard to see you as anything but a Russian troll using classic doublespeak and misdirection typical of Russian intelligence services.
