So what I expect to happen next is this...

The UN will announce their finding in a few days, which will likely be that the shells & delivery systems used in the chemical attack are not in possession of the rebel forces, but are an exact match to those known to be in possession of Assad, therefor by default the chemical attacks must of been carried by the Assad Regime and not the rebels. This might of been true if it we not for the fact that the rebel forces gained access to these exact shells & delivery systems in secret as part of the "off the books" Libyan arm deal with the CIA via BenGhazi. Basically the rebels (with full US support) used secretly purchased Libyan weapons they are not believed to have access to (but Assad is know to have) to carry out an attack in a way that even after a UN investigation would lay sole blame on the Assad regime by default.
