Part of me has always felt that Ukraine's resilient defence has, to some extent, been an inconvenience to the West as governments never expected them to stand.
There was definitely an initial reluctance to support Ukraine because it was believed to be a lost cause; when it became apparent they weren't, they were forced.
It's also now at NATO's advantage to support them beyond the protection of members' borders, but rather it's draining and destabilising their key opponent.
Maybe I'm being cynical, but the longer the war goes on the better it may be for NATO as it will diminish the threat from Russia for an even longer period of time.
The sanctions are now in place, so the damage is mainly done*. Therefore, the more Russia's government, military and economy is damaged, the safer they'll be.
I can't see Russia's military being ready for any other major operation for a good few years, at least.
*Understandably, the sanctions are also impacting on economies and thinking objectively the sooner they're removed the better. The point is it's for the long haul.
