The conflict between Israel and Lebanon began in 1948:
Israeli–Lebanese conflict - Wikipedia
"The
Palestine Liberation Organization (PLO) recruited militants in Lebanon from among the
Palestinian refugees who had been expelled or fled after the creation of Israel in 1948."
Israel was created to wreck havoc across the Middle East on behalf on western imperialists, first the UK and, now, the US.
The imperial plan was laid out in the 1980s for anyone paying attention:
Yinon Plan - Wikipedia
"The
Yinon Plan is an article published in February 1982 in the
Hebrew journal
Kivunim ('Directions') entitled 'A Strategy for Israel in the 1980s'..."
"It (the Plan) has played a role in both conflict resolution analysis by scholars who regard it as having influenced the formulation of policies adopted by the American administration under
George W. Bush, and also in conspiracy theories according to which the article either predicted or planned major political events in the Middle East since the 1980s, including the
2003 invasion of Iraq and the overthrowing of
Saddam Hussein, the
Syrian Civil War and the rise of the
Islamic State"
