WW1 is a bad example...by then corruption was way high every country was for itself...no one cared about religion had they cared they wouldnt have fallen to Nationalism! But they fell to Nation first then everything else...it served them fine here on this world....
I never ask of anything...But I do request for unity....coz I am tired of blood shed based on different sects, based on diff historic background based on different believes based on different skin colour and whatever Islam said you should not do they do....
And also united a community would be strong then separate little ones fending off every scum coming our way....
Plus we also get to travel freely like EU
I really would like to see Turkey, Iran, Iraq, Syria....but all except Turkey are danger zones
Nationalism as I said...everyone protected their interest which was money, I wonder if they will be able to buy the opening to the door of heaven with all that
