Fidel Castro debunks the ROK allegations of the sinking of the 'Cheonan'

Cuba's ailing former president 'el lider' Fidel Castro appeared for 75 minutes on the Cuban television 'mesa rondanda' [round table] on 13 July 2010. He kept mostly to foreign affairs. He began by debunking the ROK [Republic of Korea aka South Korea]--ably magnified by the US propaganda machinery--claim that the DPRK [Democratic People's Republic of Korea aka North Korea] sank the South Korean corvette 'Cheonan' in March 2010.
Dr. Castro threw the blame on the US. Well could we expect anything different from the object of more than 50 years of US effort to assassinate, overthrow, boycott, or to reduce Mr. Castro to his knees and shout 'uncle!' to satisfy Washington's vendetta?
A reasonable question, one would think. But wait a minute. China and certainly Russia--two members of the UN Security Council--did not think so. They forced the US to water down a joint ROK American resolution to condemn the DPRK for this cowardly act resulting in the loss of 46 crew. In the end, the Council deplored the sinking of the 'Cheonan' without blaming North Korea, thereby taking the wind out of the sails of South Korea's president Lee Myung bek and the endless drumbeat of US president Barack Obama ratching up day by day the campaign to condemn and sanction North Korea for the sunken corvette.
Dr. Castro may very well be on to something. No American media picked up this item:
Two academics teaching in the US Dr. Lee Seunghun [department of Physics, university of Virginia] and Dr. Suh JJ [SAIS at John Hopkins university] published in a July issue of 'Japan Focus' the following article "Rush to judgment: inconsistencies in South Korea's Cheonan Report', knocking out the pins underneath the ROK's and US' case.
Briefly, Peter Lee in the 16 July 2010 edition of 'Asian Times Online' in his contribution 'China turns netizen anger on Seoul' summarises Drs. Lee and Suh's conclusion thusly:

1. the ROK military botched the investigation.
2. twenty-fvie officers are going to be disciplined for 'shortcomings ranging from drunkenness to falsification of records' as to the sunken 'Cheonan.
3. the military will get a 'revised version' of the report when a thorough investigation of the incident is concluded.
4. more interestingly the big dering do of the smoking gun on the salvaged torpedo bearing 'the magic marker [of] Korean characters scraweld on the dredged fragments--REMARKABLY SURVIVED [emphasis GuamDiary] even when the high temperature paints coating the torpedo were themselves incincerated'.

For more details GuamDiary encourages to google the article. GuamDiary has from the beginning observed that the ROK US case against the DPRK was like a stool with three legs. Reasonable doubt cropped up at every turn in reading the assertions found the media and ROK and US government press releases. Damaging too was the selective release of the 150 page 'Cheonan report', with the advice that its full publication would 'compromise sources'. A red flag if not a red herring as to the nature of such data in spite of approval by a barrel of homegrown and foreign experts who more likely than naught had the full evidence provided to them.

So Dr. Castro may not have been speaking through his hat after all.
