Matthew Hoh's resignation letter

 Excepts from the resignation of Matthew Hoh, a US diplomat assigned to Afghanistan:

I have lost understanding of and confidence in the strategic purposes of the United States' presence in Afghanistan. I have doubts and reservations about our current strategy and planned future strategy, but my resignation is based not upon how we are pursuing this war, but why and to what end....

...Our support for this kind of government, coupled with a misunderstanding of the insurgency's true nature, reminds me horribly of our involvement with South Vietnam; an unpopular and corrupt government we backed at the expense of our Nation's own internal peace, against an insurgency whose nationalism we arrogantly and ignorantly mistook as a rival to our own Cold War ideology.

I find specious the reasons we ask for bloodshed and sacrifice from our young men and women in Afghanistan. If honest, our stated strategy of securing Afghanistan to prevent al-Qaeda resurgence or regrouping would require us to additionally invade and occupy western Pakistan, Somalia, Sudan, Yemen, etc. Our presence in Afghanistan has only increased destabilization and insurgency in Pakistan where we rightly fear a toppled or weakened Pakistani government may lose control of its nuclear weapons.
