I think Pax Christi is a group the sanctions busting French Priest, Father Benjamin, was associated with. He was a oil vouchers recipient and pal of Tariq Aziz.
I think I remember voicing a suspicion about Benjamin being connected with Pax Christi, but my recollection is I wasn't able to nail down a direct connection, just able to show that he hung around groups in the same network as Pax Christi. If my memory serves me, back around maybe February I did a search on him and Ramsey Clark and I found some sites where they were listed along with hundreds of others in the international peace movement, but nothing more direct than that. I don't doubt he has a connection to Pax Christi, I just wasn't able to find it at that time, possibly because I'm searching in English and some of Benjamin's ties would be in French or Italian. My guess would be both Benjamin and Pax Christi are linked to the World Peace Council in Europe and have mutual contacts there.
