Can someone translate this quote by Mustafa Kemal Atatürk from English to Turkish?:

"Peace at home is peace in the country. Peace in the country is peace in the world."

Tesekkurler

M.Kemal Atatürk´s famous quote is :

Peace at home, Peace in the world.

Yurtta Sulh, Cihanda Sulh. ---> Original quote, in old Turkish.

Yurtta  Barış , Dünyada  Barış.--> In contemporary Turkish.

Is there a lot of differences between old and contemporary Turkish?

In the end same meaning and ordinary Turk know many of old words.
