Trump made a deal with Saudi Arabia to sell the Saudis about $110 billion worth of weapons. 

I think Trump made a good speech and it was well presented in Saudi Arabia.

Trump wants the Muslim countries to join in the fight against extremists. 

I wonder if the Saudis will use the weapons from the U.S.A. to fight against Daesh (ISIS/IL) extremists in Iraq and Syria.

If the Saudis don't use their new weapons against  Daesh (ISIS/IL) extremists, who will the Saudis use those weapons against?

And I wonder if the other Muslim countries and leaders liked Trump's speech, agree with Trump and will help fight against Islamic extremism and terrorism.
