Georgia was moving further West, even joining the U.S.-led coalition fighting in the Iraq War in 2003. This process intensified after the election of pro-Western President Mikheil Saakashvili in 2004.
Georgia on the verge of joining NATO, but not yet subject to the organization’s collective defense agreement, Russia saw an opportunity to rein in its neighbor and demonstrate its military strength in the region.
