The first half of season seven as well as the prior DVD movie Redemption revolves around the government of General Benjamin Juma, your typical African military dictator. It is revealed that he, in concert with a Blackwater-esque American private military company, had established a large network of operatives and informants within the United States government funded through their extensive diamond mining operations.
His people try to capture the legitimate President of his country, "Sangala", who seeks to prevent the mass ethnic cleansing of his people.
Despite Juma's attempts to force them to stay out of the conflict the United States invades Sangala and meets with very little resistance but cannot find Juma. Why ? Well, therein lies the rub.
Juma, you see, is already in the United States and personally leads an attack on the White House! He and a small number of Sangalan soldiers manage to take over the entire building, holding the President hostage - though fortunately, Jack Bauer was already in the building.
The problems with this are numerous and show why the show has gotten so bad. First, Juma is an African dictator, not some terrorist. African dictators don't go on suicide missions, and that's what their attack was. They had no plan of escape. Their American allies couldn't do anything once they entered the building.
Apparently not realising that he was A) holding the commander in chief of the most powerful armed force in the history of the world hostage or B) that every gun in Washington DC would have been pointed directly at his head at this point, Juma just stands there and gloats.
But anyway, later it turns out that those private military contractors are planning to sneak a biological weapon developed in Sangala in to the US in order to commit a false flag operation.
Jack is accidentally exposed and there's the second problem. Jack spends the remainder of the season sick and unable to be, well, Jack. As a result he is sidelined in favour of Girl-Jack Renee Walker and the miraculously resurrected Tony Almeida.
