But that doesn't mean that Bosnia is tied to each and every event those folks were involved in after their departure - neither 9/11 or the Madrid attacks feature Bosnia as a central element in either their planning or execution. It is merely one of the countries the jihadis visited in the 1990's, and has about as much to do with both attacks as Afghanistan, Sudan, or Chechnya.
I don't know where you get this notion that "6 degrees of separation" has become the last word in retroactively justifying Serbia's invasion of Bosnia, but unless you disabuse yourselves of the notion, you're in for nothing but continued disappointment.
As it stands, Andan is likely to lose his job over this fiasco if he can't back up his words - in the real world, folks are sometimes held accountable for their actions and statements.
How nice it would be if FR were the same.
