Seriously, if Ehud Barak saying that Israel built these tunnels isn't enough to get you to at least question this, then you are beyond help.
Ehud Barak (Hebrew: אֵהוּד בָּרָק [eˈhud baˈʁak]; born Ehud Brog; 12 February 1942) is an Israeli former general and politician who served as the tenth prime minister from 1999 to 2001. He was leader of the Labor Party from 1997 until 2001 and again from 2007 until 2011. He previously held the posts of defense minister and deputy prime minister under Ehud Olmert and then in Benjamin Netanyahu's second government from 2007 to 2013. He attempted a political comeback, running in the September 2019 Israeli legislative election as the leader of a new party that he formed. His party merged with other parties to form an alliance called the Democratic Union, but the alliance did not win enough seats for him to become a member of the Knesset.
A lieutenant general in the Israel Defense Forces (IDF), Barak shares with two others the honor of being the most highly decorated soldier in Israel's history, having taken part in many battles and combat missions. He was appointed Chief of General Staff in 1991, serving until 1995. He is a graduate in physics, mathematics, and economics from the Hebrew University of Jerusalem and Stanford University.
