U.S. and U.K. media have had full coverage of President Trump’s despicable recent re-tweeting of anti-Muslim images and comments and his justified rebuking by U.K. Prime Minister Theresa May. 
Most of this coverage has focused on the source of the three videos that Trump re-tweeted (a far-right British political group) and the specifics of those videos: a fake Muslim attack on a Dutch boy; an extremist Muslim cleric’s destroying a statue of the Virgin Mary; and a 2013 Egyptian political clash.
Surprisingly, however, another reason why this latest example of Trump’s outrageous ignorance and ineptitude should be condemned has not been mentioned. It undercuts the efforts of Islamic allies of the U.S. to combat the misuse of Islam by extremists.
As discussed in two recent posts to this blog, Saudi Arabia, a Muslim-nation and U.S. ally, is leading a 41-member coalition of Muslim nations to do just that (Islamic Military Counter-Terrorism Coalition (IMCTC)). At the November 26 conference of this group, Saudi Crown Prince Mohammed bin Salman said, “The biggest danger of this terrorism and extremism is the tarnishing of the reputation of our beloved religion… We will not allow this to happen. Today, we start the pursuit of terrorism and we see its defeat in many facets around the world especially in Muslim countries… We will continue to fight it until we see its defeat.”
Another speaker at that conference, Dr. Mohammad bin Abdul Karim Al-Issa, Secretary General of the Muslim World League, said, “This meeting confirms the resolve of an Islamic consensus, one that takes its true meaning from the Islamic values of peace, tolerance and moderation.”
This coalition’s efforts were preceded by the similar efforts of one of its members and another U.S. Muslim-nation ally, Morocco. In 2016 Morocco was the leader and the host of another conference that created the Declaration of Marrakesh. 
That Declaration recognized that “several predominantly Muslim countries [in recent years] have witnessed brutal atrocities inflicted upon longstanding religious minorities. These minorities have been victims of murder, enslavement, forced exile, intimidation, starvation, and other affronts to their basic human dignity. Such heinous actions have absolutely no relation whatsoever to the noble religion of Islam, regardless of the claims of the perpetrators who have used Islam’s name to justify their actions: any such aggression is a slander against God and His Messenger of Mercy as well as a betrayal of the faith of over one billion Muslims.”
