I asked if you had evidence. I didn't ask if you could provide conspiracies that have been pushed by others.
For example, ISIS weapons came from US, and UK, China, and Russia, and many other countries. Because all allies countries armed Iraqi military and these supplies were captured by ISIS. Some of the weapons used by ISIS were used by Nazis during WW2. Because ISIS used anything they could get their hands on.
As I said. Do you have evidence or are you just suggesting that there's evidence based on something some blogger said?
