Abstract
The following research work has given a comprehensive elaboration of questions vis-àvis crucial legal aspects of the Second Lebanon war of 2006. The history of Jewish settlements in the occupied Palestinian lands and their activities after occupying and declaring sovereignty over these lands against Arab countries and Hezbollah has been given in the initial pages to understand the background of this conflict. These questions are closely related to ‘jus ad bellum’ which is the body of law that provides justifications for a state’s transition from peace to use of armed force and 'jus in bello’ which defines and describes code of conduct and liabilities of hostile and neutral nations along with individuals that are involved in armed conflict with each other. Most importantly, events leading to the second Lebanon war and questions regarding the assessment of this war under UN charter &interpretations of “use of force” and “armed attack” by ICJ along with analysis of Israel’s right of self-defense against Hezbollah’s actions during this ordeal will be mentioned in considerable detail as well in the latter part.
