OTher Motives for Military Presence in Afghanistan

I have found an interesting video, It is an interview, dicsussing reasons for U.S presence in Afghanistan. and Evidence, and opinions, seem to suggest that the United States may have other motives for staying in Afghanistan. Afghansitan is also a important strategic objective for the U.S Military presence in Afghnasitan gives them the power to govern and spread influence, in Asia, and would give the US strategic advantage against China, and Russia, if any war or conflict were to break out.
