Professor Ray Murphy:

The force would have to be there in the interests of international peace and security rather than to serve the interests of Russia or Ukraine. For example, there is no way the Russians would ever agree to the deployment of some kind of NATO force. I completely understand why they would not. It will be quite complex. As for Ireland participating in something like that, in fairness to the Taoiseach, I have listened to some of his comments on this and he clearly says there is a limit and that, if we do end up engaging in some kind of deployment in that sphere, we are not going to be there to enforce anything. We might be there as observers post the cessation of hostilities.
