Doomsday Clock moved forward

Well, it distresses me to call your attention to an AP article entitled "'Doomsday Clock' moves nearer midnight". Here's how it gets started:

LONDON - The world has nudged closer to a nuclear apocalypse and environmental disaster, a trans-Atlantic group of prominent scientists warned Wednesday, pushing the hand of its symbolic Doomsday Clock two minutes closer to midnight.

It was the fourth time since the end of the Cold War that the clock has ticked forward, this time from 11:53 to 11:55, amid fears over what the scientists are describing as "a second nuclear age" prompted largely by atomic standoffs with Iran and North Korea.

But the organization added that the "dangers posed by climate change are nearly as dire as those posed by nuclear weapons."

The Bulletin of the Atomic Scientists, founded in 1945 as a newsletter distributed among nuclear physicists concerned by the possibility of nuclear war, has since grown into an organization focused more generally on manmade threats to the survival of human civilization.

Now here's something else that disturbs me. You know, I check the CNN website everyday to see what the mainstream press is reporting. Perhaps you know that CNN has a U.S. edition and an international edition. Well, the Doomsday Clock story was picked up by the international edition but not the American one. So how are we to interpret that? Do Americans just not want to know? Do we not deserve to know? Has some decided that it's better if we don't know? Who made that judgment call and why?
