"String, why does the exact death toll in Damascus matter?
It was a devastating attack resulting in many deaths including kids.
In Iraq we do know that sarin and mustard were used.
Why not check these things before pontificating?"

The answer of course is that I don't trust your sources. Who is this "we" that knows so much?

"I think you should start a thread about the international trade in arms."

It's common knowledge that the US and Israel are trading in arms internationally. This is a chief export of both countries.

Who originally armed Assad Sr. before Assad Jr. took over? Why the sudden turn of interest now after both Assads have been committing atrocities for years? Sarin gas is just one of the terrible weapons that have been used in Syria. US drones are equally as harmful used in other countries. The US, India, Israel, Pakistan and Saudi Arabia all have nuclear weapons far more capable of lethal destruction of many human lives more than sarin. Why have they decided that these weapons should be kept? If anyone attacks the US with nuclear weapons, there is no defense that makes any sense.
