Right of registance and terrorism

I found that President Obama used the phrase quoted from "Mencius".
Mencius was a Chinese Confucian. To be different from other Confucianism, his theory is affirmative to revolution.
and insisted "right of resistance"of people against tyranny . Because this resistance is ordered by Heaven.
"Tenchu"(天誅)means punishment by heaven in Japan. This phrase is often used by persons who feel righteous indignation.(The famouse stealth game "Tenchu"is same meaning.)
In Japanese westernisation, these Confucian thinking came to combine with natural right which Locke or Rousseau emphasized in their works. But unfortunately, these thinking became to justify various terrorism.
"Showa-Ishin"was song for righteous indignation of young officers. Of course, this song was forbidden in public after February 26 incident.
