President Trump calls for unity against terrorism

President Trump called on Muslims around the globe to unite in the war against terrorism.

President trump addressed the leaders of 50 Muslim-majority countries, telling them they must take the lead in the fight against extremist groups like ISIS.

Muslim majority countries must take the lead in combatting radicalization.

In Saudi Arabia, President Trump made the case that countries in the Middle East should play a greater role - fighting what he describes as a "crisis of Islamic Extremism"

“This is a battle between barbaric criminals who seek to obliterate human life and decent people, all in name of religion. People that want to protect life, and protect their religion-this is a battle between good and evil," he said.

The speech on Islam, billed as the centerpiece of the Saudi visit - for a president who was highly critical of the religion throughout the campaign and proposed banning all Muslims from entering the U.S.

During his visit, he had a different tone, from years ago, calling Islam one of the world's greatest faiths and promised Muslim leaders that the U.S. will work with them to fight terrorism.

“America is prepared to stand with you in pursuit of shared interests, but nations can't wait for American power to crush this enemy for them,” he said.

The America-first president called on Muslim leaders there to eliminate what he calls the "foot soldiers of evil."

President Trump also fell victim to the age old presidential posture problem and the question of bowing in the presence of foreign leaders.

Trump lowered his head, appearing to bow to King Salman - when receiving Saudi Arabia’s highest civilian honor.

In 2012, Donald Trump blasted President Obama for appearing to bow - tweeting "Do we still want a president who bows to the Saudis?"

Saudi Arabia was just the first stop on President Trump's first foreign trip. Up next, the commander-in-chief heads to Israel for meetings about brokering Mideast peace, then to the Vatican for an audience with the Pope. From there, it's a NATO summit in Brussels and a G7 meeting in Sicily -all before coming back to Washington on Saturday.
