We need to send more weapons, simply. More heavy armour and longer range missiles. And of course get those planes there asap.
Russia's one advantage is their ability to strike from the safety of their own country - often at soft targets.
We need to be doing what we can to degrade that advantage.
It is outrageous that we still seem to fear the Russian response: maybe 16 months ago it was more understandable but they have been exposed as useless in the intervening time. Ful of sound, lies and fury, much of it possibly vodka-fuelled,
Immediate Nato membership would be my wish too but sometimes you just have to live with and accept the reality and in this case the reality is that it would mean Nato taking on Russia directly: now I would say, personally, "bring it on" but there is no stomach for that. In the meantime Ukraine needs to get the hardware and everything else it needs to destroy the invaders: do that and Nato membership will take care of itself.
