I should add that Russia desires the Baltics, which are in an awkward position to defend by NATO. Finland has a strong military and its proximity to those countries makes an incursion somewhat less likely.

That was the leading thought before we were shown how ineffective Russian conventional military is.

Indeed they demonstrated that, but don't underestimate the effect an existential crisis like this has. We will almost certainly see heavy changes coming to the Russian military. It could be that in five to ten years their military is actually capable, after both structural and strategical upgrades.

And the lines we now draw between NATO, Russia and China could well be the lines of a WW3 within a decade. Hopefully not though.

They've claimed to be doing those heavy changes for the last ten years and this is what they have to show for it.

Being cut off from nearly all advanced technology and with a terrible economy doesn't sound like a recipe for improving much in that sense either.

The more NATO expands, the higher the risk of that war. Russia joining China wasn't even a foregone conclusion, but our leaders are doing everything they can to push it in that direction.

A similar line of argument about alliances and treaties preventing war was used before the First World War. We all know how that ended.

NATO was formed with that in mind. A single treaty document publicly ratified. No secret pacts. No back-alley alliances.

It's also a bad concept. Defensive alliance is a loaded term, but people use it in arguments as if it was a well defined mathematical object.

> Defensive alliance is a loaded term

It also doesn't appear to be a very accurate description of the things NATO has been getting up to since the end of the Cold War.

"[NATO] has been involved in military operations in the Balkans, the Middle East, South Asia, and Africa"[0]

You don't have to be a spin doctor to realise that what seems like "defence" to one person is another's war of aggression.

German defence minister Peter Struck memorably said in 2004 that "Germany was also [being] defended on the Hindu Kush".[1]

Almost like "defensive weapons". Almost, because that's even worse.
