The article claims that nuclear weapons could come into play in the Ukraine-Russia war and the U.S. now could be targeted because we donated the long-ranged missiles to Ukraine. While it seems like nuclear war could be a posibilty I wonder how realistic and likely this outcome truly is. The article talks about Russia building bomb shelters were being developed at mass-production rates but I wonder how different these rates are compared to the previous production rates and if there is signifigant evidence that this threat is serious.
