Escalating the war in Afghanistan would be the wrong decision

Escalating the war in Afghanistan would be the wrong decision - CNN.com: 

Vietnam is a sadly apt analogy. Indeed, just as they did in Vietnam 50 years ago, US troops in Afghanistan are fighting a costly, intractable, and unending conflict against a relentlessly resilient asymmetric foe.
However, it's not a perfect analogy. The Vietnam War provoked impassioned debate back home, but Americans are hardly discussing the war in Afghanistan. It's completely off the radar.
It's high time we talk about this forgotten war, and especially with the Trump administration considering a new policy that would escalate US military involvement. Escalation would be a mistake, and it would further prolong a conflict that can't be won.
