World War One could have been an avoidable war with the absence of various alliances that existed between the European countries back then. All the countries could have concentrated on their own national affairs without the assistance of some other country. Stronger countries could have helped the weaker countries in a limited way totally refraining from offering assistance militarily. If these two steps would have been followed World War One could have been averted. The existence of various alliances between countries with a combination of nationalism led the whole of Europe and then the whole world into the war (www.globalyceum.com (Links to an external site.)).
