Time magazine has announced that it is launching a new weekly feature called "In Their Words" in which Presidential candidates Barack Obama and John McCain will each write a column on a subject of the magazine's choosing.

Two weeks ago, we presented dueling essays by the presidential candidates on the nature of patriotism. This week, Senators Obama and McCain face off on their strategies for Afghanistan. Their essays inaugurate a regular feature called In Their Words, in which the candidates will share a page and debate an issue of our choosing. Every week, we give you great reporting and analysis on the presidential campaign, but now we're also offering you the unvarnished and unfiltered views of the candidates so you can compare them side by side.
