Are you actually telling me that the USA had less of a responsibility with the DESTRUCTION of Syria, Iraq and the TRAINING of ISIS in them and Afghanistan than SAUDI ARABIA?
Oh boy. Here's a history lesson for you:
ISIS Weren't US Trained, The Taliban were not trained by the US directly. Various militant organisations who self identified as the Mujaheddin were. The Mujaheddin were trained and armed by the US, The Saudis, and Pakistan to liberate there country from Soviet invaders after the soviets invaded Afghanistan to ensure the Afghan communist party got into power by force.
About 7 years after the soviets pulled out of Afghanistan, The Taliban is formed and take control of 2/3rds of the country, fighting the Mujaheddin fighters who didn't join the Taliban.
So, the US Didn't even directly Train the Taliban, Let alone ISIS. They trained organisations that were to fight off soviet oppressors, and about a decade later, Organisations formed against the US in which some members were formerly in organisations trained to fight for there own freedom. Nobody at the time could have predicted this would happen, and the only reason it seems obvious now is because it had already happened before we were born.
The Taliban emerged as an opportunistic militia using the countries weakened state to gain control and enforce a strict Islamic regime. The Taliban actually fought many organisations trained by the US And won.
ISIS also was a similar story. Organisations that presented no threat to the west were trained and armed during programmes backed by US Funding to fight Gaddafi and Asaad and individuals amongst those went and joined the islamic state, fighting there previous organisations.
The middle east was fucked before America intervened, sure, its not much better now, but NATO Intervention allowed the establishment of Highly trained and well armed security forces in Afghanistan and Iraq to help fight off insurgency and establish themselves as a legitimate nation. Had America not intervened in the first place, then the USSR Would most likely held control over Afghanistan and other nations for several more years to the point where NATO boots on ground intervention against the Soviets would have most likely occurred and caused a third world war.
So please, if you're gonna take a gun control debate and turn it into a platform for you to spill anti American propaganda, at least put some time, Thought and effort into it.
