Probably factual inaccuracies, since Israel was not created by the UN (it was supposed to, but the Israelis declared Israel themselves because the UN was sitting on their hands, and took a larger area than UN had designated to Israel) and I don't recall Lebanon declaring war on Israel.
* they have done so since they were created by UN in 1948
* all neighbouring countries declared war on them then. As far as I know only one of them has since retracted their declaration of war.
Edit: Is it downvoted because of factual inaccuracies, tone, relevance or something else? Honest question, I have noe clue.
