Afghan President Hamid Karzai delivered yet another broadside against Pakistan yesterday, just before heading out to India for a state visit. He said "Pakistan has pursued a double game toward Afghanistan, and using terrorism as a means continues," closing out with a threat that "the government of Afghanistan has the responsibility to decisively fight against the enemies of independence and peace in Afghanistan."
Those are pretty bold words for a leader who can't govern his own country, much less win a war against Pakistan. While he's not wrong that Pakistan is interfering in Afghanistan, Karzai's attempt to shift blame across the border is just one more avoidance of responsibility for his corrupt and incapable government. Like most unsuccessful governments, Karzai's Afghanistan finds others to blame instead of working to improve what is in their power to fix. Pakistan sees a dysfunctional Afghanistan that the United States is about to walk away from, and is trying to create a buffer against its chaos seeping further into Pakistan or providing India a springboard for influence. Pakistan's strategy is not wrong in its assessment, but has chosen a means of influence that is ultimately self-defeating.
