What this means is that the Arab states will team together with the Lebanese, to create a booming city and country, that will finally reach that status that it deserves. Personally, Lebanon, to me, was one of those places which should have attracted more tourist interest, and given 5 years or so, it will attract a heavy influx of foreigners.
Remember Libya? The tourists are now starting to seek out places that were once considered no-gos. Beirut, which in recent years, was known as the party capital of the Middle East, will, one day, be that again.
In the meantime, some sort of ceasefire must be reached, whether that is tomorrow, or in weeks to come. After that, expect a time of consolidation, some diplomacy, and then for the rebuilding to start. Companies from the UAE, I have no doubt will be first in to invest. Emaar is perfectly placed as are some of the hotel chains.
And one day, Lebanon, will be all that it was, and more.
