For tonight's Conversations with Great Minds - Thom Hartmann is joined by Chris Hayes.

He is also the Editor-at-Large of The Nation magazine and writes on issues central to the liberal community - including what is hurting the Democratic Party - and how the labor movement is changing From Wall Street to Main Street - the wealthy elite have run roughshod over the lives of everyday Americans for the past several decades. How did we get to this point in American history - and what can be done to fix our broken meritocracy?

Edward Girardet, Writer and journalist since mid-1970s on conflict, humanitarian and media issues joins Thom Hartmann. His new book is "Killing the Cranes: A Reporter's Journey Through Three Decades of War in Afghanistan". Few reporters have covered Afghanistan as intrepidly and humanely as Edward Girardet. Now, in a gripping, personal account, Girardet delivers a story of that nation's resistance fighters, foreign invaders, mercenaries, spies, aid workers, Islamic extremists, and others who have defined Afghanistan's last thirty years of war, chaos, and strife. As a young foreign correspondent, Girardet arrived in Afghanistan just three months prior to the Soviet invasion in 1979. Over the next decades, he trekked hundreds of miles across rugged mountains and deserts on clandestine journeys following Afghan guerrillas in battle as they smuggled French doctors into the country, and as they combated each other as well as invaders. He witnessed the world's greatest refugee exodus, the bitter Battle for Kabul in the early 1990s, the rise of the Taliban, and, finally, the US-led Western military and recovery effort that began in 2001.

This Sunday will mark the one year anniversary of the beginning of the Fukushima nuclear disaster - and a year on - the disaster continues to devastate the people and nation of Japan. Towns and cities within miles of the Fukushima plant are still covered in a fine layer of radioactive dust - and have been turned into nuclear wastelands - devoid of life. Those lucky enough to have survived the earthquake and tsunami are now battling radiation poisoning and and the probability of cancer and birth defects. As hundreds of thousands of people across the world prepare to commemorate the tragedy over the course of the next month - we need to ask ourselves - is nuclear power really worth enduring such a horrible and deadly disaster? Will there ever be a way to make nuclear power a safe form of energy - or do we need to move away from it all together? Tonight we have a special edition of Conversations with Great Minds - featuring Stephanie Cooke. Stephanie is one of the world's top reporters and authors on the issues of nuclear energy and the use and history of nuclear weapons and is a real industry insider. Her articles on nuclear topics have appeared in a variety of publications - including Readers Digest - The International Herald Tribune - and GQ magazine. Stephanie first began her reporting career in 1977 at the Associated Press - and later moved to London where she covered the Chernobyl disaster for Business Week. She returned to the United States in 2004 to complete her most recent book, "In Mortal Hands: A Cautionary History of the Nuclear Age." Currently - Stephanie is the editor of Nuclear Intelligence Weekly - part of the Energy Intelligence Group.
