What is the  use of self defence

The controversy regarding the use of self defence is the 'anticipatory self-defence'. Those with a restrictive view state that it no longer exists as oppose to the permissive view. The anticipatory self defence did achieve recognition; it states that lawful force can be applied. According to UK and USA, in situations where the threat of attack is eminent and overwhelming the use of force is allowed and legal. For example, Israel branded the attacks on Iraq as pre- emptive, which led to a controversy and, thus, their argument was turned down. The cumulative self defence on the other hand was not given importance and acceptability.
