President Trump, in a much anticipated speech on terrorism to Muslim leaders in Saudi Arabia, on Sunday said: "Terrorists do not worship God. They worship death."

Speaking of "bloodshed and terror," Trump said: "There can be no coexistence with this violence. There can be no tolerating it. No accepting it. No executing it. And no ignoring it. Every time a terrorist murders an innocent person, and falsely invokes the name of God, it should be an insult to every person of faith."

Addressing Saudi King Salman, Trump said he hopes "today we begin a new chapter that will bring lasting benefits to all of our citizens."

"I stand before you as a representative of the American people to deliver a message of friendship and hope and love," Trump said at the Arab Islamic American Summit. "That is why I chose to make my first foreign visit a trip to the heart of the Muslim world. To the nation that serves as custodians of the two holiest sites in the islamic faith."

"America is a sovereign nation," Trump said at the King Abdulaziz Conference Center in Riyadh. "And our first priority is always the safety and security of our citizens. We are not here to lecture. We are not here to tell other people how to live. What to do. Who to be. Or how to worship. Instead we are here to offer partnership based to shared interest and values to pursue a better future for all of us."

Trump said "with God's help this summit will mark the beginning of the end for those who practice terror and spread its vile creed. At the same time, we pray this special gathering may some day be remembered as the beginning of peace in the Middle East, and maybe all over the world. But this future can only be achieved through defeating terrorism and the ideology that drives it."

Added Trump: "If we do not stand in uniform condemnation of this killing, then not only will we will be judged by our people, not only will be judged by history, but we will be judged by God. This is not a battle between different faiths, different sects or different civilizations. This is a battle between barbaric criminals who seek to obliterate human life and decent people all in the name of religion."

In opening remarks, Saudi King Salman said he shares with Trump the feelings of "constructive cooperation to reject extremism, work on fighting all forms of terrorism, stop its financing and its propagation, dry up its sources and stand firm in confronting this scourge that poses a danger to all of humanity."

In the days leading up to the speech, there was speculation whether Trump would use the phrase "radical Islamic terrorism" — a phrase he embraced during the campaign — during his remarks. About two hours before Sunday's speech, the White House released excerpts indicating Trump would not use that exact phrase, but refer to "Islamist extremism."

While delivering his speech Sunday, Trump seemed to stray away from the prepared text, actually using the term "Islamic extremism." "That means honestly confronting the crisis of Islamic extremism, and Islamists and Islamic terror of all kinds," he said.

During the presidential campaign, Trump — who once famously called for a temporary shutdown of all Muslims entering the United States — criticized Democratic presidential nominee Hillary Clinton and then-President Barack Obama for not saying the phrase "radical Islamic terrorism."

"These are radical Islamic terrorists and she won't even mention the word and nor will President Obama. He won't use the term radical Islamic terrorist, no," Trump said during a presidential debate with Clinton in St. Louis in October. "To solve a problem you have to be able to state what the problem is or at least, say the name. She won't say the name and President Obama won't say the name. But the name is there. It's radical Islamic terror. And before you solve it, you have to say the name."

Trump is on his first foreign trip as president. He arrived in Saudi Arabia on Saturday. Over eight days, Trump is also visiting Israel, the Vatican, Belgium and Italy.

Speaking of Iran, Trump said: "But no discussion of stamping out this threat would be complete without mentioning the government that gives terrorists all three: safe harbor, financial backing and the social standing needed for recruitment."

"It is a regime that is responsible for so much instability in that region," he said. "I am speaking of course of Iran. From Lebanon to Iraq to Yemen, Iran funds arms, and trains terrorists, militias and other extremist groups that spread destruction and chaos across the region. For decades Iran has fueled the fires of sectarian conflict and terror. It is a government that speaks openly of mass murder, vowing the destruction of Israel, death to America, and ruin for many leaders and nations in this very room."

"Among Iran's most tragic and destabilizing interventions, you've seen it in Syria," Trump said. "Bolstered by Iran, Assad has committed unspeakable crimes, and United States has taken firm action and response to the use of banned chemical weapon by the Assad regime."

He added: "Responsible nations must work together to end the humanitarian crisis in Syria, eradicate ISIS and restore stability to the region, and as quickly as possible."

Referencing a $110 billion Saudi-funded defense purchase, Trump called it a "historic agreement" and said: "We'll be sure to help our Saudi friends to get a good deal from our great American defense companies."

"My meetings with King Salman, the crown prince and deputy crown prince have been filled with great warmth, goodwill and tremendous cooperation," he said.
