how a small war turns into a big war
... This allows the countries to have back up anytime there is a war. Usually it is not used for one but in times like World War I it was a very big thing for both sides. When a big county has about two to three other countries helping them out, it can really boost the level of hardness to win the war. The war started out small because it was only two countries at first, but after the allies join the war it gets bigger and bigger depending upon the different allies each country has to help them out. The war involved so many countries because lots of countries wanted different parts of land and things they thought that by fighting in the war the allies could gain that land or that power they have always craved even though they are the smallest country around.
