King Bumibun last appeared in public earlier this month when he briefly left the hospital since then palace medical bulletins have noted blood infections, fever and lung inflammation. He is said to have improved, but national anxiety persists. The Arab parent, Crown Prince, Mahavajira Longkorin, has not attained the exalted level of adoration given to his parents. This month he let a bicycle ride and events seen as demonstrating to a nation under army rule, but the military backs the Crown Prince to succeed as father. There's never been an event like this in Thailand before. It's my first time to bike with a lot of people and demonstrate our unity. But the prince remains a more remote figure who last year divorced his third wife. Some have speculated his sister, Princess Csirin, who is broadly admired for her philanthropic work and educational endeavors could become a successor, but she has not been formally designated as an heir to the throne. Discussion of royal succession is taboo. In commenting about the fate of a monarchy, can result in lengthy prison sentences under Thailand's harsh Les Majestylal. They're also alarmed at the spike in harsh prison terms delivered in such cases by the military courts, which themselves fail to meet international human rights standards, including the right to a fair trial. Most highs have known only one king. His passing will thrust this nation into deep mourning. It may also prompt prolonged soul searching and hush discussion about the transformation of the Chakri dynasty. Steve Herman Vioe News, Bangkok.
