“We wanted to be in Nato… we are facing the biggest army in Europe by ourselves,” said Vadym Prystaiko.
Conflict between Russian-backed separatists in eastern Ukraine and the Ukrainian military has continued since 2014, although a shaky ceasefire is in place.
Western and Ukrainian intelligence services have suggested an invasion or incursion could happen some time in early 2022, after Russian forces amassed on the border.
Meanwhile, Russia has accused Nato countries of “pumping” Ukraine with weapons and said the US is stoking tensions in the region.
Its main demand is to stop any expansion of Nato to the east, with Deputy Foreign Minister Sergei Ryabkov saying after recent talks that it is “absolutely mandatory to ensure that Ukraine never, ever becomes a member of Nato”.
