SOUTH VIET NAM SUICIDE IN MANY FORMS A SOUTH VIETNAMESE NOVELIST AND POLITICIAN NAMED NGUYEN TUONG TAM SENT HIS SONS OUT TO BUY A BOTTLE OF WHISKY ONE NIGHT LAST WEEK . FOR A WHILE HE SAT DRINKING WITH THEM AT HIS HOME IN SAIGON . " MY SONS, I FEEL VERY HAPPY TONIGHT, " HE SAID . " I AM GOING TO DIE VERY SOON . " SUDDENLY HE KEELED OVER, WAS RUSHED TO A HOSPITAL WHERE HE DIED NEXT MORNING . IN HIS GLASS WAS FOUND A LETHAL DOSE OF CYANIDE . NOVELIST TAM, 58, WAS A REVOLUTIONARY LEADER IN INDO-CHINA'S WAR AGAINST THE FRENCH . BUT AFTER INDEPENDENCE IN 1954, HE GREW INCREASINGLY DISENCHANTED WITH THE AUTHORITARIAN RULE OF SOUTH VIET NAM'S PRESIDENT NGO DINH DIEM . FORTNIGHT AGO, DIEM'S GOVERNMENT CHARGED TAM AND 34 OTHERS WITH TREASON BY CONSPIRING TO OVERTHROW THE PRESIDENT IN AN ABORTIVE COUP ATTEMPT IN NOVEMBER 1960 . IT WAS JUST TWO DAYS BEFORE THE SCHEDULED TRIAL THAT TAM COMMITTED SUICIDE, AND HE EXPLAINED WHY IN A NOTE HE LEFT BEHIND . " THE ARREST AND TRIAL OF ALL NATIONALIST OPPONENTS OF THE REGIME IS A CRIME THAT WILL FORCE THE NATION INTO THE HANDS OF THE COMMUNISTS, " HE WROTE . " I OPPOSE THIS CRIME, AND I KILL MYSELF AS A WARNING TO THOSE PEOPLE WHO ARE TRAMPLING ON OUR FREEDOMS . " DRAGGING FEET . DIEM'S GOVERNMENT MOVED QUICKLY TO HEAD OFF DEMONSTRATIONS OVER TAM'S DEATH, POSTHUMOUSLY ACQUITTED HIM OF ALL CONSPIRACY CHARGES AT THE SAIGON TREASON TRIAL . AT THE SAME TIME, THE PROSECUTORS TRIED TO IMPLICATE THE U.S . AS BEING BEHIND THE 1960 COUP ; THE CHARGE WAS VIGOROUSLY DENIED BY THE U.S . AT THE END OF THE TRIAL, GOVERNMENT JUDGES SENTENCED 20 DEFENDANTS TO PRISON TERMS RANGING FROM FIVE TO EIGHT YEARS ; NINE OTHERS WHO HAD FLED THE COUNTRY AFTER THE ATTEMPTED COUP WERE SENTENCED TO DEATH IN ABSENTIA . TAM'S SUICIDE AND THE SAIGON TRIAL SERVED ONCE AGAIN TO STOKE SOUTH VIET NAM'S SMOLDERING RELIGIOUS AND POLITICAL CRISIS . LAST MONTH BUDDHIST MONK THICH QUANG DUC BURNED HIMSELF TO DEATH ON A SAIGON STREET CORNER IN PROTEST AGAINST RESTRICTIONS IMPOSED ON THE COUNTRY'S 12 MILLION BUDDHISTS BY DIEM'S PREDOMINANTLY ROMAN CATHOLIC REGIME . AFTER A SERIES OF NATIONWIDE DEMONSTRATIONS, THE GOVERNMENT, UNDER U.S . PRODDING, YIELDED TO BUDDHIST DEMANDS AND GRANTED THEM EQUAL RELIGIOUS AND POLITICAL STANDING WITH THE NATION'S 1,500,000 CATHOLICS . BUT INFLUENCED BY HIS BROTHER, NGO DINH NHU, WHO BELIEVES THAT THE BUDDHISTS ARE RED DUPES, THE MILITANTLY CATHOLIC DIEM HAS DRAGGED HIS FEET IN IMPLEMENTING THESE CONCESSIONS . MANY VIETNAMESE BUDDHISTS, SAYS NHU, " HAVE BECOME FANATIC, LOST THEIR COMMON SENSE, AND ARE READY TO FOLLOW ANYONE WHO KNOWS HOW TO EXPLOIT THEM UNDER THE BANNER OF RELIGION . " THIS WAS THE KIND OF DOGGED ANTI-BUDDHIST ATTITUDE THAT HAS DANGEROUSLY UNDERCUT GOVERNMENT SUPPORT . ALREADY ONE GENERAL HAS RESIGNED HIS FIELD COMMAND IN PROTEST OVER GOVERNMENT BUNGLING OF THE BUDDHIST ISSUE . SIMPLE REASON . DIEM'S INTRANSIGENCE HAS DISMAYED U.S . OFFICIALS, WHO FEAR THAT MOUNTING BUDDHIST DISCONTENT CAN ONLY HINDER THE WAR EFFORT AGAINST THE VIET CONG, JUST WHEN IT IS BEGINNING TO GO WELL . OVER THE PAST YEAR, GOVERNMENT FORCES AND THEIR 14,000 U.S . MILITARY " ADVISERS " HAVE VASTLY INCREASED THEIR MOBILITY AND STRIKING POWER AGAINST THE RED GUERRILLAS . MORE THAN 7,000 " STRATEGIC HAMLETS " HAVE BEEN BUILT, NOW PROTECT 8,000,000 VIETNAMESE FROM VIET CONG RAIDS . DESPITE ALL MISGIVINGS, THE U.S . STILL STANDS BEHIND DIEM FOR A SIMPLE REASON THAT HE HIMSELF SPELLED OUT IN A BLUNT WARNING LAST WEEK : " FOR A MOMENT, IMAGINE THAT ANOTHER GOVERNMENT REPLACES THIS ONE : IT COULD NOT HELP RESULTING IN CIVIL WAR AND DREADFUL DICTATORSHIP . " WASHINGTON HAS CONSIDERED ALTERNATIVES TO DIEM, BUT FEARS THAT THE CONFUSION OF A COUP COULD ONLY BENEFIT THE VIET CONG AND MIGHT END UP WITH A REGIME NO BETTER THAN THE PRESENT ONE . THUS U.S . AMBASSADOR FREDERICK NOLTING, WHO IS SOON TO BE REPLACED BY HENRY CABOT LODGE, RETURNED TO SAIGON FROM WASHINGTON CONSULTATIONS LAST WEEK WITH A PERSONAL MESSAGE OF CONFIDENCE FOR DIEM FROM JOHN KENNEDY . BUT NOLTING ALSO LIGHTLY RAPPED DIEM ON THE KNUCKLES FOR LETTING THE BUDDHIST CRISIS CONTINUE . " THE U.S . STANDS FOR AND SUPPORTS FREEDOM OF RELIGION FOR ALL PEOPLE, " HE SAID . " IT WOULD BE A TRAGEDY IF THE GAINS AGAINST THE VIET CONG WERE WIPED OUT BY DISSENSIONS AMONG VIETNAMESE CITIZENS, WHO DESIRE ABOVE ALL FREEDOM OF CHOICE FOR THEMSELVES AND FOR THEIR COUNTRY . WATCHING ONE BUDDHIST DEMONSTRATION IN SAIGON LAST WEEK, NINE U.S . REPORTERS WERE JOSTLED BY GOVERNMENT POLICE AND HAD THEIR CAMERAS SMASHED . THE COPS SAID THE REPORTERS HAD STARTED THE ROW . THE VOCIFEROUSLY ANTIDIEM U.S . PRESS CORPS IN SAIGON PROTESTED TO PRESIDENT KENNEDY .
