123 countries involved in the war
Countries that were members of the UN (United Nations) sent troops to the war.
World War 1 left the countries that were involved with a major distrust of people from other countries. Resentment was caused in countries such as Germany and Italy who lost land during the war.
I believe that they were involved in the 6 day war with Israel in 1967.
Only Spain and the US were involved.
they got involved in war because the others declared war :)
Europeans (APEX)
They had alliances with countries that were involved.
It is much easier to name the four countries that wereinvolved: Israel, Egypt, Jordan and Syria. Other countries might have gotten involved, but the war was over in six days, before any other country had decided on that.
about 52 countries.
Beside Bosnia, Croatia and Serbia & Montenegro were involved too, which inputs that this was not a Civil war. Actually it was aggression of other two countries on one independent country accepted by UN and EU.
