Either one of two things happened.
1). Assad did indeed use them and he needs to be held accountable.
2). The rebels used them and made it look like Assad used them just to pull other nations into the battle. In this case, the rebels need to be held accountable for their actions.
There is no way to determine either conclusion, at this point in time, because the evidence that could point to either one has been destroyed. However, many are asking why Assad would use WMDs if he is winning the war, which by all accounts he is.
This war will end tragically for someone, but I hope our forces are not drawn into what could become a full blown out regional war, especially in the light of Biblical prophesy and what the Bible says will surely happen to anyone who tries to oppress or attack Israel, who we all know will also be drawn into the battle.
Here’s a story someone floated earlier. Don’t know what to think of this.
“U.S. ‘backed plan to launch chemical weapon attack on Syria and blame it on Assad’s regime’” From January, 2013.
I don’t like how this portrays the US. Still, the story is out there, probably not accurate.
