My take on this is different.Trump had consistently indicated throughout the campaign that he had zero interest in Syria other than to attack ISIS. Shortly before the attack, Trump's cabinet ministers confirmed that his administration had no interest in 'regime change' in Syria. After the attack, Trump said  nothing for almost two days. However, several commentators suggested that Trump had inadvertently contributed to the attack by giving Assad the impression that the U.S. didn't care about what he did to his own people. There were also comments about his initial failure to criticize Syria and Russia. Trump hates being criticized and his sudden reversal in policy suggests an impulsive action, at least partly in response to the criticism. In this case, his national security team agreed with his action. But what he has a similar impulse to respond militarily to some new provocation, maybe from North Korea that his security team thinks is unwise. Will he listen to them?
