In 2000, when I was assigned to Operation SOUTHERN WATCH at Al Kharj, Prince Sultan Royal Suadi Air Force Base, we were explicitly told to have NO CONTACT with the French during our in-brief. We were not to accept rides offered to/from Ops Town, we were not to sit with them at meals, we were not to associate with them off-duty AT ALL.
And the reason was explicitly stated: the entire French contingent held an intel-collection brief. They were there for one reason: to spy on us, and that's what they did. They were excluded from ALL briefings, and anything they needed to know re: life on PSAB, they were breifed apart in a sanitized version, as befitted their status of an adversary collection threat.
And it got worse: there WERE examples of French contact and intel sharing with Iraqi military, DURING the period of actual engagements between Iraqi and Alied air component forces. Let me make this clear: the French were discussing Allied operations while those ops were being engaged by Iraqi air defense forces.
