It's been a year since the US pulled out of the Iran nuclear deal ad some experts warn that the threat of a worldwide meltdown is the worst its been since the darkest, most dangerous days of the Cold War.
If other parties to the Iran nuclear agreement don't work to ease sanctions pressures, Iran could walk away from the deal, as US President Donald Trump did one year ago.

A new look into HBO's upcoming miniseries "Chernobyl" gives us a deep look into the nuclear power plant disaster that rocked the then Soviet Union and continues to impact Ukraine to this day. Director Johan Renck spoke with Carol Hills about why he feels this story needs to be told.
In the nuclear arms race against the US, the former Soviet Union performed more than 450 nuclear tests in an area known as the Semipalatinsk Test Site — also known as the Polygon — from 1949 to 1989. Winds blew the nuclear fallout and radioactive dust into neighboring villages, affecting anywhere between 500,000 to 1 million people.
