Terrorists generally use the methods of taking hostage, sabotage, hijacking, assasination, threat and bombing. James Adams pointed out in his book named as ''The Finance of Terrorism'' that most of the terrorists believes in rightfulness of their cases. Adams noted that fear and immorality hold a terrorist organization together. Terrorists who can even kill their own brothers and sisters, admit the organization as their real family. Terrorists obtain weapons from the markets in the regions having lack of authority.
Terrorism refuses the policy and aims at making civilization unworkable.
There are seven countries supporting terrorism according to the US sources. These are Iraq, Iran, Libya, Syria, Sudan, Cuba and Northern Korea. Iran is the most dangerous supporter of the terrorism. Media of mass communication has an important role on terrorism. Television and radio channels and newspapers give large place to the bloody terrorist actions, so terrorist organization succeed in promoting their actions against humanity.
