President Trump’s desire to pull US troops out of Syria is based on the flawed belief that the fight against ISIS has been won. However, this is not the case, argues Robin Wright of The New Yorker. Leaving now risks the caliphate emerging again. It currently has around 3,000 fighters available and would benefit from US troops leaving. The power vacuum could benefit other entities, from Hezbollah to Russia. It could prove to mirror the mistake of leaving Iraq too early, without engaging in the proper nation building that ensures stability. America’s national interests are best served staying in Syria and preventing the rise of terrorists.
