Living in Austria it is pretty peaceful here. But there are serveral layers of peace imo. The obvious one is a military internal or outside conflict the country is tied to.
The second layer are internal conflicts of society. I doulbt there are countries that are fonished or their way to the perfectly peaceful society.
As long as a Paygap, descrimination towards race, gender, sexuality etc. exists there is plenty to do for a society sriiving towards peace.
And even once this open minded equal society exists there are many internal conflicts, as there are always backwards thinking homophobic racist hillbillys fighting this equal society.
