What is there to explain? I'm sick of our country being world police on a case by case basis centered only around what benefits us. I'm watching the hearing and the opening statement was just so fake.
It's completely absurd to say hey you can kill people this way, but the second you start killing them that way you better watch out! Nevermind the fact our allies have used white phosphorus against civilians, which is also banned. This is all nothing more than a show, the underlying reasons for attacking Syria is obvious, chemical weapons are just an excuse.
