The U.S. has tired of its longest war, debating only the size of the small force it will leave behind, mostly for training purposes. The Taliban continues to have many strongholds in significant parts of the country. And Pakistan continues to support the Taliban from across the border-support that is likely to expand as America withdraws and Islamabad seeks to fill that power vacuum.
So Karzai might be playing an erratic game of brinkmanship in his negotiations with Washington, but he might also be trying to navigate a post-American Afghanistan. While American troops might well remain and some American aid will continue, Afghanistan is going to look very different in 2015 than it does today.
