President trump helping the Saudis launch a new global center as well. Jonathan Karl, traveling with the president and starting us off tonight. Reporter: Donald Trump and the Muslim world. An image that not long ago would have been impossible to imagine. Here in the birthplace of Islam, the man who had portrayed muslims as the problem, offering a message of unity against terrorism. This is not a battle between different faiths, different sects, or different civilizations. This is a battle between barbaric criminals whoeek to obliterate decent people and human life. This is a battle between good and evil. Reporter: In the audience, the leaders of more than 50 Muslim countries. Vier virtually the entire islamic world. A remarkable moment for the man who just a year ago said -- I think Islam hates us. There's something, something there, there's a tremendous hatred there. Reporter: And for the candidate who had proposed a total and complete shutdown of all muslims entering the U.S. A prohibition that would have applied to everyone in this audience. But today -- I stand before you as a representative of the American people to deliver a message of friendship and hope and love. Reporter: But he did issue a challenge. A better future is only possible if your nations drive out the terrorists and extremists. Drive them out. Drive them out of your communities, drive them out of your holy land. And drive them out of this Earth. Reporter: The president's call to action notably left out a signature phrase, which he had long ago insisted was crucially important. Radical islamic terrorism. Reporter: It wasn't just semantics. Trump had hammered both Barack Obama and Hillary Clinton for failing to say radical islamic terrorism. Now, he portrayed the enemy of a godless enemy of all religions, including Islam. Religious leaders must make this absolutely clear. Barbarism will deliver you no glory. Piety to evil will bring you no dignity. Jon, the administration is touting the speech as a step in the right direction, and hoping to build on that momentum for the next leg of the trip? Reporter: They're not predicting an outbreak of peace, as the president goes to Israel and meets with the Israelis and Palestinians, but they do believe this will give momentum to restarting peace talks. The Arab nations that were here see two main enemies. Iran and ISIS. Neither of which are Israel, and in fact those are the same enemies Israel sees. So, the administration hopes they will see more support than in the past. Jonathan, thank you. The events in the mideast unfolding against the drum beat of controversy at home.
