Iran won in 2015 Iran Deal.
Just see previous news to 2015 and the incredible world pressure that Iran endured from USA vassals in the period 2010-2013 when Iran war to Western vassals had seem imminent and unavoidable.
After 2015 Iran situation changed drastically, yes, it came back threats with Trump, but in a different way.
In 2010-2013 almost whole world harassed Iran under USA pressure, even UN allowing intercept Iranian ships (never applied, but approved resolution), China (Hu Jintao China, not Xi Jinping China) stopping buying oil to Iran, Russia ignoring Iran in UN, stopping selling them S300. GCC allowing their airspace use to attack Iran nuclear program and so on.
All that stopped forever after 2015, now the situation is different, it's only tiny troublemaker Israel facing Iran.
