The pressure that Washington puts on the world is Always financial..
Even the little wars we start.. it is either designed to bankrupt our opponents directly, or the region which cause local financial political cascade..
Close to nuclear war... no way... humans are just not THAT stupid... that stuff gets everywhere and doesn't cleanup for 100 years. and the high yield probably 200-300 years..
According to your mainstream media or your own belief system?
Step one, ISIS only developed under which President - Obama, the travesty and destruction in the Middle East after Bush's Iraq invasion, again Obama. Whole sale support via weapons and money again Obama, so your conclusion that YOU don't get involved with crimes against humanity doesn't hold here at all. Since all of these atrocities happened under Obama's watch and support it's nice to live in a fantasy world where destroying whole countries won't have any long term consequences for you.
Step Two - 9/11 was the prime example of the Saudi's paying their supporters to harm the US, Obama thought long and hard to stop publishing the investigation conducted by the FBI on who was truly responsible for that event. Obama even tried to ban US citizens from taking the Saudi's to court for compensation, yet the senate through out his disgusting veto and joined together (for the first time in years) to overthrow his objection.
Hence the US people got to see in full Obama's contempt of them by trying to cover up all the details of the 9/11 disaster. It clearly showed who was responsible with funding terrorists in this world and having the right to hold them responsible in a Court (very important). This is something Obama and his clown posse dreaded so much because if the Saudi's can be taken into court so can he be held responsible in the future by any nation who suffered under his rule.
Obama also funded a huge Drone System worth Billions of dollars from US citizen's, taxes funding his exploration into bombing people and villages throughout Pakistan, Afghanistan and Iraq. He was so proud that he became the first President who openly cheered on the killing of various people on the globe that included whole families which included women and children, that never deterred him in any way.
Also Hillary went on her crusade of demonizing Russia and that Putin has to be stopped by taking back Crimea, she was quoted on many occasions repeating that very same statement. So now if she won you can bet loading up her ships to invade Crimea on Russia's doorstep wouldn't lead to a nuclear confrontation, where have you been living? This was on the brink like Cuba's Missile crisis and you lot didn't seem to care or know about it, hoping it was some kind of Steven Segal sad script or a another Schwarzenegger Epic?
Your main stream media continues to fill your world with the English Royals and Kardassian travesties but the REAL World knows what is going on, maybe we are not as blinded by your own media when it comes to knowing exactly what is happening around the globe these days.
