@NahnCee,
That is not the consensus I see. Doing nothing means that Afghanistan is lost. We do not have the luxury of engaging in endless theoretical disputes while demanding zero casualties. We must act in response to emerging threats even when knowing that such actions are usually imperfect and messy. While doing that we must continue to also act proactively to change conditions so as to force our enemies (I hate the term adversaries) to behave in a more predictable reactive manner. Being pro-active is even more likely to provoke criticism. We have to expend ourselves in Pakistan partly because doing so supports our position in Afghanistan. We can not abandon Afghanistan because we cannot let Putin surround the oil regions. If we did pull out we would have to kill more people in leaving than we will by staying.
