Sen. Ted Cruz

The Berlin Wall will stand till the end of time.

And Reagan, with a twinkle in his eye, he said, don't you understand?

This is the whole point of the speech.

Less than three years after he gave that speech, the Berlin Wall was torn to the ground.

And it wasn't torn down by American tanks bulldozing it.

It wasn't bombed to the ground by American missiles.

It was the power of American leadership, of truth, of standing up against tyranny that resulted in the Berlin Wall being torn down.

So when I talk with optimism about what could happen and what I hope will happen in Iran and Venezuela and Cuba, it is with that example that when America stands and leads,

freedom is an incredible and a powerful thing and shining a light of truth on tyranny and oppression can be transformational.
