Should Muslim Nations Denounce Radical Islam?

Not just nations, but every person who disagrees with radical Islam must make it clear at every opportunity. They must communicate this with the mainstream media. Not doing so makes it appear that they agree. This is critical now, when opinions of Muslims are becoming more and more unfavorable. Normal Muslims must clarify their values. Those who do not publicly denounce radical Islam and clarify their values, cannot complain if non-Muslims develop negative opinions of them all based on radical acts.
