Russian officials have threatened that a possible decision by the West to allow Kyiv to use donated weapons to strike deeper into Russian territory would result in a major escalation of its war against Ukraine that could include the use of nuclear weapons.
Former Russian President Dmitry Medvedev, now deputy chairman of Russia’s Security Council, warned on September 14 that Kyiv could be turned into a “gray melted spot” if restrictions against Ukraine’s use of Western weapons were loosened.
It wouldn’t have to be a nuclear retaliation. Once Putin opens the nuke door though, then NATO is all out of reasons to not mobilize all conventional resources and unleash hell.
If they open that particular box, the only option would be to strike against each nuclear site in Russia. Because once that started there is no reason the Russian threshold for usage would not just lower over time.
At the same time Ukraine would start striking nuclear power plants in Russia. Russia has a lot to lose here.
Additionally, with the firepower at just the US’ disposal, we could level almost every major pop center in Russia. Waves of Tomahawks, ICBMs and bombers could do it without the US putting boots on the ground. We nearly did this with Baghdad back in 02.
