It is the few differences you need to listen for in Trumps speeches.
His speeches are designed this way because it makes the differences stand out. That is the real messages he is putting out.
Just like the MSM/Mockingbird system uses repetition to train the sheep to believe their message, repetition by Trump makes the differences stand out. It makes the real message click in the minds of the listeners.
Not only are we in a information war but also psychological one for the mental freedom of the PEOPLE of the World.
At least that is my thought.
