Fascinating peek inside the latest Atlantic (in a cover story shared with sister pub National Journal) on the perilous security of Pakistan’s nuclear weapons. Payoff grafs:

…instead of moving nuclear material in armored, well-defended convoys, the [Pakistani government] prefers to move material by subterfuge, in civilian-style vehicles without noticeable defenses, in the regular flow of traffic…according to a senior U.S. intelligence official, the Pakistanis have begun using this low-security method to transfer not merely the “de-mated” component nuclear parts but “mated” nuclear weapons. Western nuclear experts have feared that Pakistan is building small, “tactical” nuclear weapons for quick deployment on the battlefield. In fact, not only is Pakistan building these devices, it is also now moving them over roads.

What this means, in essence, is this: In a country that is home to the harshest variants of Muslim fundamentalism, and to the headquarters of the organizations that espouse these extremist ideologies…nuclear bombs capable of destroying entire cities are transported in delivery vans on congested and dangerous roads. And Pakistani and American sources say that since the raid on Abbottabad, the Pakistanis have provoked anxiety inside the Pentagon by increasing the pace of these movements. In other words, the Pakistani government is willing to make its nuclear weapons more vulnerable to theft by jihadists simply to hide them from the United States, the country that funds much of its military budget.
