Used them but what else would you expect from the likes of GWB and Cheney? Evil incarnate.
As always, Glenn Greenwald really lays it out:
Slightly more than two months after he was awarded the 2009 Nobel Peace Prize, President Obama secretly ordered a cruise missile attack on Yemen, using cluster bombs, which killed 44 innocent civilians, including 14 women and 21 children, as well as 14 people alleged to be “militants.” ...
... The Obama administration’s refusal to join the Convention has caused tension and controversy even with its most subservient allies, such as Britian, a signatory to the treaty. ...
But now the Obama administration is moving far beyond a mere refusal to join the convention banning these munitions. According to The Independent, the U.S. is playing the leading role “to torpedo the global ban on cluster bombs” through a “proposal that would permit the use of cluster bombs as long as they were manufactured after 1980 and had a failure rate of less than one per cent.” The paper also reports that despite Britain’s long-time role in supporting the ban, its conservative government is now backing the Obama administration’s efforts to codify their use. The Pentagon claims that newer cluster bombs can be used more safely, but activists have documented that “many modern cluster bombs have far higher failure rates on the field of battle than manufacturers claim.”
There is good news on this issue, Britain unites with smaller countries to block US bid to legalise cluster bombs. Of course, the good news on cluster bombs has nothing to do with Obama, but rather, opposition to his policies.
