PERUGIA, Italy - In a hidden corner of Rome's busy Fiumicino Airport, police dug quietly through a traveler's checked baggage, looking for smuggled drugs. What they found instead was a catalog of weapons, a clue to something bigger.

Their discovery led anti-Mafia investigators down a monthslong trail of telephone and e-mail intercepts, into the midst of a huge black-market transaction, as Iraqi and Italian partners haggled over shipping more than 100,000 Russian-made automatic weapons into the bloodbath of Iraq.

As the secretive, $40 million deal neared completion, Italian authorities moved in, making arrests and breaking it up. But key questions remain unanswered.

I suspect the Italians unwittingly stumbled upon a joint Iraqi/U.S. scheme to help equip opposition groups in Turkey, Iran and Syria. Perhaps this also explains what happened to literally thousands of weapons purchased by the U.S. for Iraq that are now lost. This story is just unfolding and it won't be very pretty.
