LAST THURSDAY, WE CARRIED THE HEADLINE Martial law in Thailand. It was inevitable. Last Thursday was the 34th anniversary of martial law in this country, and that martial law should also be imposed in a neighboring country on the very eve of it was too rich to ignore. If that suggested however that what happened in Thailand last week is the same thing that happened in this country 34 years ago, start disabusing yourself of the thought. The differences are patent. First off, Ferdinand Marcos martial law was about ruling forever. He mounted a dictatorship because his second term as president was ending and he couldnt find a way to get around the ban. He tried to change the form of government from presidential to parliamentary by bribing the members of the Constitutional Convention, but his shenanigan was exposed by an honest old man named Eduardo Quintero.
