IMO, they are going to try to hit the Republican Convention, by ground and possibly by air, while GW is there. Presumably, they will have secondary targets if they can't get close enough to the convention center.

This is the first source that I've read that mentions her nationality. The South African government has acknowledged the theft of some 7000 blank passports.
