Last night as you know President Trump unveiled it was billed as a new approach to afghanistan. The 30minute speech marked a major policy reversal for donald trump who in the past has urged the United States to get out of afghanistan.

A core pillar of our new strategy is a shift from a timebased approach to one based on conditions. Ive said it many times how counterproductive it is for the United States to announce in advance the dates we intend to begin or end military options. We will not talk about number of troops or our plans for further military activities. We are a partner and a friend, but we will not dictate to the Afghan Peo
