Russia Not Backing Down

On the other hand, Russia denies that it intends to attack Ukraine. Still, it has threatened to use military force if its demands, including the rejection of Kyiv's NATO membership ambition, are not granted.
Last week, Moscow presented its demands to the West during security talks in Geneva that produced "no breakthrough," according to observers.
