On Syria, Trump should be wary of Obama's 2011 mistake in Iraq

Preparing to withdraw U.S. ground forces from Syria, President Trump should pay attention to what happened after former President Barack Obama's hasty 2011 withdrawal from Iraq. Because Obama's withdrawal led to the increasing influence of Iran over Iraqi politics and thus invited Shia sectarian policies targeting Sunnis. In turn, these policies helped foster the rise of ISIS and led to Obama being forced to return forces to Iraq.
