If the Trump administration via the military and CIA had proof so quickly after the alleged chemical attack in Syria, regarding who was responsible, then that means they knew before it happened and as it was happening and did nothing to stop it by at least alerting the world what they supposedly knew was in the works.
After seeing how the military, CIA and FBI over the last few months have responded to President Trump, by trying to undermine his presidency, I wouldn’t trust the information they give him.
