To many who want right-wing Japanese Prime Minister Shinzo Abe to clarify his views on history and apologize for the Japanese military's atrocities during World War II, his address to a joint session of the US Congress on Wednesday came as a huge disappointment.

In the first-ever such speech by a visiting Japanese prime minister, Abe only expressed remorse over Japan's role in WWII. He did not call the war "aggression" on the part of Japan or mention the coercion used by the Japanese military in the comfort women outrage, when Asian women were forced into sexual slavery. These are just two of many issues raised by Abe's controversial views on historical facts.

The speech clearly shows that Abe has not changed his views on this 70th anniversary of the end of WWII. The Japanese prime minister has caused more pain to people in neighboring countries in the past years by questioning whether WWII constituted an aggression on the part of Japan and denying that coercion was used by the Japanese military in running the appalling comfort women system.

In his speech, Abe just kept focusing on Japan's post-WWII role in the world. But Japan's positive contribution to the world in the past decades does not grant Japanese leaders and politicians the right to whitewash history. We have not seen German leaders try to rewrite Nazi history or deny the Holocaust on the grounds that post-war Germany has made great contributions to world peace and prosperity.

It is true that people may hold different views, but should we allow differences when people like Abe try to deny "aggression" and "coercion" on the part of Imperial Japan?

It is hard to believe that Abe's remorse expressed on Wednesday is genuine at all, since he even refused to express an apology to the people who have suffered from Japanese militarism.

If Abe is true to holding the general stance on history of successive Japanese prime ministers, then why it is so difficult for him to say the word "apology" explicitly, or just repeat words in the 1995 apology issued by then Prime Minister Tommich Murayama on the 50th anniversary of the end of WWII. Demanding an apology from right-wing Abe is certainly not as outrageous a request as some might think.

While Abe's stubborn revisionist views may be nothing new, it is shocking that US leaders, including President Barack Obama, have chosen this time to collaborate with him, without demanding he make an apology and clarify his views on history. No senior US officials have touched on Abe's controversial views.
