Definition: In this task, a passage will be given and the goal is to identify an event from the passage. An event is defined as a single word representing something that happened, is happening, or may happen. An event can be factual or hypothetical, positive or negative, certain or uncertain. While most events are based on verbs, an event can also be based on a noun (ex. storm, snow, rainfall) or a copula verb (is, was, been, etc.). The event must not be a pronoun or an adjective. For noun events with multiple words, use the last word in the phrase as event.
Input: Passage: Former premier Benjamin Netanyahu, who is favourite to regain the Likud leadership, insisted security and military strength would bring peace to Israel as he took a swipe at his arch-rival Sharon. "Our peace is dependent on our strength ... and not on endless (territorial) retreats," he said in his first press conference since Sharon's split.
