Yes
Because a large number of countries were involved - not just the main, well - known combatants.
A hot war is most dangerous to the army combatants and civilians, but a cold war can do just as much damage to the countries involved without a weapon being fired.
The countries that were the primary combatants of World War 1, started building their military long before the war started. These countries were rivals and if one country expand their military, then their rival would do the same. After some time these countries had large enough militaries of their own to start a war.
nothing
War in which the combatants use nuclear weapons.
