Is Afghanistan turning in to Diem's Vietnam ?

Telegraph: Reports that President Hamid Karzai of Afghanistan is trying to bounce the USA in to an early election in Afghanistan. The early election would be fraught due to the military and weather conditions. As with Diem it seems President Karzai is not listening to Washington D.C, a election now would be fraught between attacks by the Taliban/Terrorists and the severe weather conditions in country. It seems from the Telegraph report that President Karazi want to keep on to power till the election, his term ends before the suppose new election. Why it can be asked does Karazi want to stay in power, if he was no longer President he would become an open target, one has to see his narrow point. At the moment Karazi is protected by the USA Special Forces, would the USA still give him protection if he was no longer President. The new Obama Administration has a low opinion of the Karazi Government, its lack of reform of Afghanistan is a major issue in D.C. So to the question, as Diem would not listen to D.C, the powers that be in D.C gave the green light to remove Diem, will Obama allow President Karazi to be removed, whats in the best interest of the West might not be in the interest of President Karazi. At the end of the day the removal of Diem in Vientam was a disaster, thus better to keep the Devil you know, because the next leader could be worse.
