Its fatalistic to say nothing will change no matter what happens.

The first step towards a true democracy is democratic elections.
And the first step towards a dictatorship is rule at the point of a gun, AKA a military coup.

Those who endorse military coups as a kind of political check and balance are certainly heading in the wrong direction for harmonious state of democracy. Its like putting the fox in charge of the hen house.

The only way to achieve reconciliation is through free and fair democratic elections. It wont solve all the problems associated with the widespread corruption infecting Thailand, but it is the first step in the right direction.

The heavy handed murderous treatment of political protesters by the military/government, draconian political censorship of the media, imprisonment of political opponents and blatant double standards by the judicary are precisely the very things the masses are objecting to. These are the products of corruption let run wild through militaries intrusion into politics. The road to a dictatorship and eternal rebellion. Oppression does not promote harmony or justice.
But of course, oppression backed by military force is the only way a dictatorship can stay in power.

Sure, such deep rooted corruption which has in fact become an accepted part of the Thai culture can not be contained overnight simply through democracy. But it can be contained eventually if the people are given a voice in government through the democratic process. Conversely, the current oppressive regime backed by the military simply promotes more corruption and abuse of power.

Thailand is at a political fork in the road now, the people have the numbers to force democracy verses the dictators with the guns and tanks. Thats the big picture.
