none of those two books are quoted how am i supposed to know if and to what extent they dispute hirst's book the quote you do adduce though horribly pov to be honest in no way implies that was a casus belli for the invasion of lebanon as for the two other sources i added today the book is peer reviewed and therefore is fit for wikipedia the editorial is syndicated in a mainstream source the independent and has an extremely notable author when the subject is israel palestine and lebanon robert fisk it more than surpasses wikipedia's notability standards and i just added a third book about israel's military history
