There is hardly any international or domestic issue on which a consensus exists in the present-day Russia. Virtually all politically active Russians strongly oppose deployment of a NMD system by the United States.
Views differ only on the way of how to respond to the Washington's intention.
Moreover, the DPRK has announced an indefinite moratorium on further tests and has expressed a willingness to eliminate its ballistic missile program in exchange for technological aid in the peaceful space exploration. By that time the DPRK will hardly exist in its current form, it will undergo reforms, signs of which are already starting to emerge. It is equally obvious to the Russian observers that North Korean leaders are not suicidal maniacs who are prepared to attack the United States and be immediately obliterated by the American missile response. Those leaders in Pyongyang have been slow in introducing even economic reforms fearing that changes may undermine their power. Pyongyang authorities realise that an attack on the U.S. or American allies will deprive them of not only power, but of their very lives.
