War has learned and evolved throughout the history, these days war is conducted through military campaigns, which includes: armed conflict, intelligence, troop movement, propaganda, aircraft, bombs and missiles.
Terrorism, on the other hand, has been described as the threat of violence, or other harmful act committed for political or ideological goals. The main goals of terrorists are to spread fear among the world population and get global attention for their actions in order to accomplish their goals.
The most common terrorist tactics include; car bombing, aircraft hijacking and suicide attacks. Almost every country and organization have different definitions for terrorism, therefore, it is still impossible to give an official one. Up to now, the United Nations has not accepted, nor given definition for terrorism.
If we compare these two, we can see that both of them have violence as their main subject, also: armed conflict, bombs and missiles, propaganda and intelligence. War has aircraft and troop deployment, while terrorism has believers and people willing for sacrifice.
What makes them different is that war requires mass organization, governments, countries and thousands of volunteers and military personnel, while terrorism can be performed with just one or two individuals. Maybe the biggest difference is that terrorism sometimes does not choose the targets, and as a result, most times, innocent people get hurt and die. War, on the other hand knows its targets, but in war innocent people also dies. Just in war, victims are euphemistically called "Collateral Damage".
