Mr. Chair, perhaps I'll start, and General Balfe may wish to add something.
With respect to the first part of your question, Mr. Goldring, our assessment is that absolutely the conflict is only and entirely being sustained by Russian support for the separatists. That is support as in materiel and training given to the separatists and the intervention of Russian units directly in the conflict. Absent that piece, it would have been possible to achieve a settlement to this issue a long time ago—well over a year ago, in fact.
With respect to the opportunities for sharing information that's gathered from satellite imagery, you mentioned the convoys. I would note that there's been a fair amount in the public domain, often gathered by media and other sources, that has documented visually and in other forms the entry of Russian convoys supplying various forms of—well, it's hard to determine what. Certainly the presence of convoys has been made clear and is well known.
It's also our impression, partly through information shared with partners in NATO, that the Russians are not actually trying very hard to disguise the volume and frequency of the support they're providing the separatists. Undisguised or barely disguised Russian units are present in Ukraine.
I'll turn it over to the general, if that's okay.
