The result of any such invasion of the Ukraine would surely be disastrous for Russia, win or lose against Nato? that conflict would mean trade sanctions against Russia too and a much weaker Russian military.No they're not bosom buddies, but at present they have more common interests than discordant interests. They both understand that they have far greater probability of achieving their goals by working together in areas of mutual interest.
I don't know. I think that they are having the hard word put on them by three particular FVEY partners and there's more stories in the media about the PRC threat so the public are becoming more aware. The usual suspects are decrying it as China bashing and / or we are going to ruin our economy, but more are taking notice and seeing past that. I have made a habit of reading the comments and there appears to be a change in tone with a strengthening of resolve towards a stronger stance against China. Some have said that we don't have enough ships, planes, and soldiers. Although it's totally unscientific anecdotal evidence, I do think that the public attitude towards China is becoming harder and towards Defence more favourable.
Another point is that the government has been hardening its stance towards the CCP / PRC and in the last six months has given NZ businesses warnings to diversify their markets away from China. We do know that Grant Robertson, Minister of Finance, has been trying to place the $20 billion defence upgrades on the back burner because of his COVID-19 spending. From memory he is one of Uncle Helen's acolytes so isn't defence friendly. Given their history and ideological bias, I am like you not optimistic but I think (hope) that their hand will be forced in this by public opinion and our FVEY partners.
China then might see a weakened Russia as an opportunity like they did with Veitnam after US and allied forces left.
