So, WHO was Putin contacted by? WHY won't he say who it was? WHY did President Bush just let it hang in the air without a comment?
Choices for nations or individuals being warned that Putin has told Bush and their secret is no longer safe:
France
Syria
China
Iraq(although since Saddam is gone I think he would have named them)
Germany
And now, getting to individuals who might have called Putin telling them they were going to help Afghanistan against the Americans:
Jesse Jackson
Bill Clinton
Madeline Albright
Al Gore
As much as I dislike all of the individuals you named I find it hard to believe they would approach Putin. Afghanistan was another failure of the UN, for years they sought a way with which to deal with the civil conflict and rise of the Taliban. For years they failed. There were many interests, factions and agendas afoot there. In any event, I suspect Iran or perhaps dissidents in the region, even certain elements who reside in Pakistan. And I further suspect that they called on Russia for arms and money, not overt support. This could well be the reason Putin said we would be sorry for going to Iraq, he knows that in the aftermath of victory comes the extremists and ongoing, bleeding unrest.
