Every military intervention is costly and the current one is no exception. It costs a lot of money to keep soldiers on the streets, and their presence spooks tourists and investors, and interrupts the process of democratic development.
The costs will be even greater if the end result is a repeat of the 2006 intervention which — after succeeding in preventing an imminent bloody clash between the forces supporting the government and those opposing it — failed miserably to prevent the same group of corrupt politicians from coming back, in many respects, even stronger. Their subsequent corrupt practices and disregard for civility are the key factors contributing to the sustained street protests that led eventually to the current military intervention.
As in 2006, this coup came amid what appeared to be an imminent bloody clash between the forces supporting the government and those against it. The present group of generals apparently has learned something from 2006; they have, therefore, not boxed themselves in by specifying the length of the transition period leading to the next parliamentary elections.
