Government officials of the United States have been busy apologizing to countries around the world for the huge embarrassment and political damage caused by the confidential diplomatic cables released by the anti-secrecy website WikiLeaks two weeks ago.

One important explanation it owes to the world, however, is whether it was behind the arrest of WikiLeaks founder Julian Assange in London last Tuesday on charges of alleged sex crimes in Sweden.

People are naturally questioning the timing of the arrest and the refusal of bail for Assange, although some $150,000 in surety has already been guaranteed.

Somewhere there must be a confidential US diplomatic cable that would shed light on this.

New York Congressman Peter King has called on the US government to go after Assange and to prosecute the New York Times, which published some of the cables. Senator Joe Lieberman has also suggested investigation into the New York Times and described its action as "an act of bad citizenship".

Secretary of State Hillary Clinton has depicted the leak as an attack on the fabric of responsible government. President Barack Obama has condemned the WikiLeaks' actions as "deplorable." The US government is considering legal action against WikiLeaks.

Under such pressure, Amazon.com, Visa, MasterCard and PayPal have all suspended their services to WikiLeaks. And the WikiLeaks website is no longer accessible in the US.

The US has also been trying numerous ways to press charges against Assange, including using the outdated World War I-era Espionage Act, although some cables suggest that some US diplomats should also be worried if that happens.
