Violence that is deemed secular, on the other hand, is often necessary and sometimes praiseworthy, especially when used for the purposes of bringing the blessings and peacefulness of liberalism to places like Vietnam, where freedom has been repressed. This is even more the case when secular violence is deemed necessary to contain or prevent religious violence. The twenty-first-century confrontation between the West and the Islamic world provides many examples of this type of rhetoric.
