So to make up for an error in judgement by POTUS (to pull troops out of Syria), he now has to make another costly mistake of imposing sanctions on Turkey. As they say 2 wrongs don't make a right. You see, from US perspective, a sanction on Turkey is not viewed as a mistake,...but it is to the emerging debt market as any ensuing collapse in the Turkish economy could result in an unintended contagion risk for the emerging debt market.
This may well go down as the greatest misjudgement by a US president in modern history that will have potential long lasting geopolitical shifts in the NATO alliance that will only serve Russia's circle of influence in the long run.
Trump's use of economic sanctions/tariffs as weapons in his approach of punishing his adversaries is a fundamental problem for a global economy that is under seige. A wounded person that is being subjected to stress after stress would finally cave in - no different is the world economy. Despite the markets resilience to climb walls of worries , as you erect more walls (self-imposed) at some point it is more than likely to break the camel's back.
