"We'll cut the whole of our nuclear stock...?"
Unfortunately Husson does not show how to ensure honesty during the inventory and dis-armament processes. Suppose an armed country diverts a few nukes from their publicly stated stockpiles (just in case) or an emerging nuclear power decides to park a few dirty bombs under several of their adversary's cities (also just in case).

The North Koreans know all about tunneling and may have already assisted Iran, Syria?, in the packaging of the bombs and methods to guarantee underground delivery either acting unilaterally or with the aid of a confederate. For example, as for tunneling, there are many desolate and unmonitored desert areas that surround cities of the middle east. In any case, parking weapons for later use can be found during the fall of the USSR, where the KGB had to retrieving pre-positioned nukes inside U.S. cities. Internet based news articles on this subject temporarily appeared and then soon after, quickly (and mysteriously) vanished. Finally, the whole concept of WMD's and their delivery systems have not reassured us as to how the criminal element, in particular, those who specialize in contraband transportation will be completely removed from this disarmament equation.
