Hope springs eternal.
Revolutions of the past (France, Russia) began at a low profile level.
Then proceeded to revolution "proper".
Kerensky of the Mensheviks in Russia (Feb-Oct 1917), followed by Lenin and the Bolsheviks (November 1917 to 1989).
This guy is the Thai Kerensky: solid member of the bourgeoisie, been to America and spika de English, and is a social democrat who will not upset the apple cart and (therefore) the real people who rule Thailand.
He will be approved by the State Department. (Say no more.)
Of course, his foes are not the Bolsheviks, but rather those who will watch carefully to ensure that their economic interests are not threatened. They will let him rule until he attempts to do something "democratic".
Rinse and repeat.
