I would like to say yes we can we are capable of that ,Yet human nature through historical legacy shows that we are not capable at present of harmony ,The system we have that controls our very existence is geared for WAR. Until we change the system by which we in our daily lives we exist we will perpetuate war continually,History shows us the path to the future .The way things are does not mean that they cannot change ,It means we need to change as a populous mentally in order to enact change worldwide, From within we will the outwardly & only then will be ready to move forward knowing that peace is with us ...Remove the fiscal system of money as we know it ,is the first step ... 2nd is the ability of the leading classes to acknowledge that we are all the same ,mostly liquid with a skin covering ... only then will peace be possible .I fear peace will come when we are at time when nature has no more to give & by then it will be to late for peace will have no one to be shared with...
