No, we will not. The human race will always want to fight to gain what they want.

World leaders will always have a need to grow economically and strategically in order to maintain power and leadership. Land that has strategic value will always be causation for war, for example the suez canal, which is a perfect trade route used to export oil to the western world. Diverse religious teachings are also cause for the continuation of war. As highlighted in the palestine-israeli conflict, in which both parties view the same territory as their rightful land and despite numerous attempts at peace negotiation the war continues.
