You are denying the agency of the people living there and/or are clueless about the country..
US and Israel started the Lebanese civil war and the enmity between the Christian and Muslim populations?
Well in a way.. at least the Palestinian refugees were a huge shock that shifted the scales. But the balance was very tight and the country would have blown up eventually anyway.
You can’t build a democracy when each half of the population hates the other half and considers that their ideological views and their ways of life are incompatible. Even US is learning that the hard way (again..)..
