Robert Casey actually said...

"The treaty does not compromise the nuclear force levels we need to protect ourselves and our allies."

"The treaty does not infringe on the flexibility we need to maintain our forces, including bombers, submarines, and missiles, in a way that best serves our national security interests."

"With the classical notion of deterrence, there are consequences before which an aggressor would recoil. In the world of suicide bombers, that calculation does not compute in any comparable way."

"Once nuclear weapons are used, we will be driven to take global measures to prevent it from happening again."
