'What will hold back the Russians?' Zelenskyy responds to new US peace proposal

We are already in a kind of confrontational conflict with Russia and that they are using obvious military force to put pressure on European countries that are supporting Ukraine whilst also conducting classic subversion, sabotage and other covert actions in Europe. But we're not looking at an imminent Russian invasion of European NATO territory and giving that impression probably both downplays existing European military capability, it reduces our deterrent effect, but it also doesn't look that credible and probably causes some people to switch off. So that's what I mean when he I say that there is a delicate balancing act here. Now on Ukraine...The general view is that the Russians will be too tempted to... try and come back for more...some kind of temporary ceasefire might work, but it would require the Europeans to demonstrate they can put their forces where their mouth is in terms of a reassurance force"
