The noble Lord makes a very good point. The recent attacks by the Russians are driven by numbers of people as much as by ammunition. NATO, its allies and other interested parties are co-ordinating a massive effort to get as much ammunition and required military support into Ukraine as possible, at the request of the Ukrainian armed forces, to ensure that they can hold and repel any additional Russian pressure. I will quote the Answer to the Urgent Question:
“Russia’s newly formed northern grouping of forces has attacked Ukraine’s Kharkiv region, taking control of several villages”.
The border town of Vovchansk is almost certainly an immediate Russian objective and is currently contested between Russian and Ukrainian forces. It goes on:
“By opening up an additional axis of attack, Russia is almost certainly attempting to divert Ukrainian resources away from other parts of the frontline and to threaten Kharkiv, the second largest city in Ukraine”.
It would take very substantial forces to overwhelm, and we do not believe they have them.
