1. Former Russian President Dmitri Medvedev has suggested that a Russian defeat in Ukraine could lead to nuclear war, while former UK Prime Minister Boris Johnson has dismissed the idea.
2. There is no exact template for mutiny or the sudden disintegration of an army, and the Afghan army's collapse in 2021 provides an example of what could happen if the Russian army mutinied or collapsed.
3. If the Russian army were to collapse, there would be a risk of nuclear war as Moscow would issue an ultimatum that Ukraine must not infringe into areas of Donbas under Russian control before 24 February and, above all, that it must not enter the Crimean Peninsula.
The article is generally reliable and trustworthy in its reporting of facts and events related to the potential consequences of a Russian military collapse in Ukraine. The article does not appear to be biased towards any particular side, as it presents both sides of the argument – former Russian President Dmitri Medvedev’s suggestion that a Russian defeat in Ukraine could lead to nuclear war, and former UK Prime Minister Boris Johnson’s dismissal of this idea as nonsense. The article also provides examples from history – such as the British Army on the Western Front in WWI and the Afghan army’s collapse in 2021 – which help illustrate what could happen if the Russian army were to mutiny or collapse.
However, there are some points which are missing from consideration in this article. For example, it does not explore possible counterarguments to Medvedev’s suggestion that a Russian defeat in Ukraine could lead to nuclear war; nor does it provide evidence for this claim or discuss other potential risks associated with such an event. Additionally, while it mentions US President Joe Biden’s likely response to such an event (leaning more towards caution), it does not provide any detail about his position or explore other possible responses from other world leaders. Finally, while it mentions French President Emmanuel Macron and German Chancellor Olaf Scholz sending urgent messages to Ukrainian President Volodymyr Zelensky regarding his troops’ advance into Donbas and Crimea respectively, it does not provide any detail about these messages or their contents.
