What do you think are the main causes of war today ?   I ’ d say the main reason is poverty . Countries and their people get frustrated because they have so little . If their neighbors have some resources , they try to steal them by military force .   It seems that a lot of wars nowadays are really civil wars . People from different ethnic groups in the same country sometimes fight for power in that country .   Several of those civil wars have been going on for years and years . It seems they will never end .
