In 2007, Al Gore won. He put politics over principle. He was pro-business, anti-union, pro-war, anti-peace, and no friend of the earth.
His "Earth in the Balance" book was more theater than advocacy. His so-called "green" credentials were used to further his pro-corporate/anti-populist/imperial agenda.
Numerous others like him comprise the Nobel Committee's hall of shame. Four US presidents stand out. In 1906, Theodore Roosevelt won. He once said he'd "welcome almost any war, for I think this country needs one."
He was honored for sponsoring the Spanish/American war and Philippines genocide. In May 1902, Senator George Hoar denounced him on the Senate floor, saying:
"You have sacrificed nearly ten thousand American lives - the flower of our youth. You have devastated provinces. You have slain uncounted thousands of the people you desire to benefit."
"You have established re-concentration camps. Your generals are coming home from their harvest bringing sheaves with them, in the shape of other thousands of sick and wounded and insane to drag out miserable lives, wrecked in body and mind."
"You make the American flag in the eyes of a numerous people the emblem of sacrilege in Christian churches, and of the burning of human dwellings, and of the horror of the water torture."
Having done that and more, perhaps he deserved two Nobels. He wanted Pax Americana enforced through the barrel of a gun.
