How would they stop it? Surely if they shoot Russian Aircraft or sink Russian ships they risk starting WW III?
I don't think so. It can go on for some time, but ultimatelly West will be forced by internal reasons to stop it.
West cannot allow RF to bomb third countries in general. Certainly not Ukraine. In Syria for example RF is invited by Syrian government.
Without similar legitimisation, any direct military action in europe is unlikely.
Direct military force application by USA extremelly possible. Longer that lasts, bigger chance USA will intervene.
Agree he doesn't need to do anything. But he has warned about crossing Russia's red lines and said there may be a Military response if Russia's concerns are not responded to satisfactorily. So I think he will do something. It could just be an announcement of permanently basing troops or an Air Wing in Belarus. He has repeatedly said he is not invading and I don't believe he will invade.
No one really knows. Invasion is not in RF interests. But, decision makers of RF are not really tied to RF interests.
One thing for sure RF proper is basically off limit no matter what. It means any military action will be outside, which in turn make risk calculation for people in power in RF somewhat unpredictable.
Yes there will be Sanctions either way but their severity may be different. And yes West can keep sending shipments after the conflict stops. But Russia can start bombing them again. A bit like the situation in Syria, Iran sends arm shipments destined for Lebanon or Palestine, Israel takes them out. But some probably get through.
Well, for starters Ukraine have somewhat potent air defence. RF have somewhat outdated technology. If western powers start to move modern air defence systems to Ukraine it can prety much stop any possible RF air campaign.
Even more so if they give combat planes to Ukraine and say lease airfield in some NATO country.
This games can be played by both sides after all. As You said no one will go to WW3, so we will have local war, same is arab-israeli wars, or korea war, or vietnam war.
Which is not ideal for anyone. That why I said that RF will probably prefer ground invasion, or none at all.
Interesting that Russia is a guarantor of Ukraine territorial integrity, didn't know that. Not sure that it means much at this point.
But I disagree it would be better to go all out. Anyway let's hope Russia does not go all out, it would be a sad day for Humanity.
Well, best outcome is RF will deescalate. Or build some military base in Belarus as a response, or something like that as long as it is not direct military action. After all they not really promised one.
