"I have to say that it's very few countries that are willing to look back at its past and apologize for its act, or make amends for its act, as the United States had one"

In this quote, Robert Matsui is highlighting the rarity of nations that are willing to acknowledge and take obligation for their past actions. He particularly points out the United States as an example of a country that has actually done so. This could be translated as a criticism of other nations that have actually not taken comparable steps towards reconciliation and recovery. Matsui's words also recommend that the act of asking forgiveness and making amends is a challenging and courageous one, which the United States ought to be commended for doing so. Overall, the quote highlights the significance of acknowledging and gaining from previous mistakes in order to move forward as a society.
