"Numerous terrorist hostage situations have occurred throughout the world since the explosion of terrorist acts in the late 1960's, and each country involved has had to make a decision on when the optimum time of armed intervention should occur. This study was conducted to provide a comparative analysis of the methods used by different countries which have dealt with terrorist hostage situations. Such information should enhance future government intervention policies formulated for dealing with these specific hostage situations. The following countries were used as a basis of analysis in this study: United States, West Germany, Israel, Italy, England, Spain, and France."
