First, I want to start with the question

"What mean peace?"

Peace means when everyone lives together and they understand with each other.

In my country isn't peace because a part of that is invaded by Russia. 

But they must not be here because there is Moldova part. 

That piece of is named Transdnestrian region.

In my country history wasn't always peace because all neighbouring countries want to have this territory. 

Example Turks want to have much territory and invaded almost all countries from Europe.

Was in history peace?

At this moment not in all countries is peace because that countries want power.And that power lead to war and all people knows when is war isn't peace.

When is peace is:

Power

Income and assets

Safety
