Inside Edition is an Americannewsmagazine television program that is distributed in first-run syndication by CBS Media Ventures. Having premiered on January 9, 1989, it is the longest-running syndicated-newsmagazine program that is not strictly focused on hard news. Though it does feature the latter, the rest of each day's edition mainly features a mix of infotainment stories, entertainment news and gossip, scandals, true-crime stories and lifestyle features.
ISIS was created by US. To destabilise and regime change Syria leadership. When plan did not go well, US stopped at funding it. IS started looking for western hostages and beheading them if no money was paid.
Eventually as Russia stepped into Syria, IS had no choice but to invade Iraq. And US seek Iranian help to halt IS advances. Suleimani, which US under Trump eventually assassinated, was iran's general. US killed their own ally just because he was on the way to negotiate a peace deal with insurgents. That is how mischievous and wicked the US is.
Iran has nothing to do with IS.
