And considering the Russian response to our development on hypersonic missiles and IRBMs. They must have realize they have no defense against ours. And they are watching our weapons development. To the point they had to respond with this.

The Russian military has warned that any ballistic missile headed toward the country
will be considered nuclear-armed, and one that warrants nuclear retaliation. The warning comes after reports the
U.S. is working to develop long range missiles capable of striking Russia. The U.S. has not developed these weapons in a vacuum, however, and there’s an argument to be made that Russia has only itself to blame.
Senior officers in the Russian military General Staff
told Krasnaya Zvezda (Red Star) there's no way to determine if an incoming ballistic missile is fitted with a nuclear or conventional warhead. As a result, the Russian military would be obliged to prepare for the worst-case scenario.
“Any attacking missile will be perceived as carrying a nuclear warhead. The information about the missile launch will be automatically relayed to the Russian military-political leadership, which will determine the scope of retaliatory action by nuclear forces depending on the evolving situation.”
