Wait, so your proof of claim "county A is fighting in country B" is that there were some weapons manufactured in country A found in country B? Do you realize what follows if I say county A is the US for example?
Regarding "training Shia insurgents", do you know that Houthis are Zaidis and Iranians are Twelvers? Do you have any evidence of claims you make about training with the "Imperial Guard" (are we doing Star Wars now)?
