Western diplomats seem to remember Hun Sen requesting U.N. help in June 1997 to set up a tribunal to try these very leaders for genocide -- but that was long before the strongman won a dubious national election this fall and secured his grip on power. Why stir up trouble now? "We should dig a hole and bury the past and look ahead to the 21st century with a clean slate," Hun Sen told reporters Monday. Considering that the two men bear much of the responsibility for more than a million Cambodian deaths while they were in key leadership positions, the forgive-and-forget strongman has a lot of shoveling to do.
