“Peace at home, peace in the world” means that if a country is peaceful inside, it can help make the whole world peaceful. It says that people should live well in their own country and also be friendly to other countries. When there is no fighting at home, it is easier to have peace everywhere.
Atatürk said these words because he always believed that a peaceful country means everything. He was such a smart, intelligent, loyal, and brave person. He only wanted to have peace in the world and for his country to be good.
Being a good country can change so many things. For example, if you have smart people in your country, they can invent useful things, or they can be good doctors for your country. Then tourists can come to our country because we are a good nation and there are good artworks in Türkiye. If they come from other countries, we will have peace. So, as you can see, Atatürk’s quote ‘Peace in the country, peace in the world’ is a very true statement.
