Russia has recently built a new missile that can sneak past our anti defense missiles. But know this, the Russian lie early and often. Early in the Cold War, we thought they had more deliverable nukes then they actually had. If I remember correctly, they only had four that may have hit their mark, but they told us they had many more then that. BTW, their missiles were not accurate and that is why they built big nukes (more megatonage).
anti missile defense, I should say.
We don't want anti defense missiles :-)
