I think you need to go back further than that.Ok. This makes sense now. I wouldn't have called Lebanon a predominantly Christian country at any point in time, but it probably has the largest population of Christians of any Arab State.
Technically, there are almost as many Christians still in Lebanon as there are Muslims. But that's beside the point..
The reason that the economy and quality of life in general went to sh!t in Lebanon is not because of the Muslim population. The Muslims and Christians in Lebanon lived in relative peace and prosperity for generations, while the country was the jewel of the Middle East in terms of tourism and finances.
But after the 1967 Arab-Israel war, there was a huge amount of Palestinian refugees who came to Lebanon. This is significant, because included in this influx of refugees were THOUSANDS militarised Palestinians, led by Yasser Arafat, and they systematically began ****ing up the country to achieve political gains.
It was not about religion!
I'm only bothering to say this because I feel like you are misrepresenting the situation, and coming to incorrect conclusions, and then trying to incite fear by saying "just you wait!". I think that's quite ignorant and unfair.
