"Our involvement could effect higher standards of transparency, independence, integrity, more effective witness protection, meaningful victim participation, and adequate anti-corruption measures," he writes.

While America has thus far declined to support the court politically or financially, other donor nations have begun to suffer from "tribunal fatigue," Kerry writes. A modest injection of U.S. dollars could help reinvigorate their support.

"Day by day, survivors die without seeing any accountability for the horrors that were committed, and without lending their voices to the record of history," Kerry writes. "A successful tribunal for Cambodia will continue the essential process that began with the Nuremberg trials of setting a standard for accountability and sending a message that the world will never forget."

As an American citizen, I would have to agree with Kerry that a $2-million contribution is necessary, though modest. Given our country's historical involvement in the region, we Americans should -- at the very least -- support a process that can bring any measure of justice to those who suffered partly because of U.S. actions (and inaction).
