It will be interesting seeing the US condemning Syria for using WP by claiming it is a chemical weapons, while turning a blind eye toward Israel when Israel used WP weapons in Gaza in 2008/2009

Text of the Chemical Weapons Convention can be found here. In it are all the confusing definitions
http://www.armscontrol.org/act/1997_04/cwctext
Syria has not signed nor ratified the CWC. Five countries total have not signed the CWC. Angola, Egypt, North Korea, South Sudan, and Syria
Israel has signed but not ratified the CWC. Only Israel and Myanmar have signed but not ratified the CWC
Kinda makes it a bit rough to hold Syria or Israel accountable to a treaty they did not sign/ratify.
