The Rus Strategic Rocket Force is very capable and well funded. I was stationed in Western Europe. I had almost unlimited access. I worked PEN -AIDS (penetration aids) AKA electronic countermeasures.

If you think the Rus can not destroy the 20th largest cities in the US, I would say you are dreaming. Sure we can destroy a 100 of the largest cities in Russia. Trust me when I say, they do have a great and effective ICBM (intercontinental ballistic missile) force.

Just because the "Special Military Operation" in Ukraine is a huge failure does not mean a nuclear warhead on a missile cannot hit Kiev.
