I honestly think Trump actually made a move that could inflict much more damage to Turkey and Erdogan overall than any military retaliation ... and as bonus , NATO is in a pickle , and no US troops come in harms way ... People very often forget that todays wars that are waged are truly economic ones . The ones we see with lethal force are small in scope compared to the economic ones . If USD / TRY keeps rising , youll see massive problems ...  Then it wont be about Kurds in Syria ... but it will be unrest across the whole Turkey . And those who are more informed can see that Iraq is already now on the critical point , with major protests that escalated into pure violence lately . It means Iran , Turkey , and eventually even Israel , arent far beyond .
