Facing these circumstances, Mr. Somchai doesn't have any good options. Dialogue with the PAD may be all but impossible after the violence this week. He could call a state of emergency, which would give more power to the military and police to enforce law and order, although that could turn out to be embarrassing if they didn't follow orders. A third option is to form a unity government and share governing powers with the opposition Democrat Party, albeit at the risk of looking weak. He could also hunker down and wait for the PAD to wear out -- although this could take a long time, seeing as the PAD is constantly rotating in new "protesters" from the countryside.It seems to me that moving as much government business as possible out of Bangkok and up to Chang Mai is an option well worth considering. Having so much power concentrated in Bangkok has not proved particularly healthy for Thai democracy.
