That genuinely scares me.
It’s a concern, but it’s something that was admitted six or seven years ago. And no doubt there is more that we haven’t been told (after all, we only found out about it because Wikileaks released it). The terrorist in question – Sheik Mohammed al-Someone Or Other – may well have been bluffing, he may have been telling the truth and the device found, or they may have been sold a dummy; there’s a legendary story of the Russian government leaking stories of “red mercury”, a fictional, but highly-important nuclear compound to the Russian press – anyone looking to acquire red mercury was clearly trying to purchase or build a nuclear device, making it easier for the Russians to find them (and one Serbian warlord allegedly spent millions of dollars on “red mercury”, only to find he’d bought a container of strawberry jam).
Reprisal attacks are very definately a concern for the world now that bin Laden is dead. But while the War on Terror might have dragged out for a decade, if there’s one thing the world’s intelligence service has proven, it’s that they’re very good at stopping terror attacks. It’s very likely Obama tipped off the world’s leaders about the Abottabad raid shortly before it went down, so that we can be prepared for when al’Qaeda come looking for blood.
