Good luck dealing with Hezbollah with mere cash.

Edit: Judging by the downvotes, people aren't aware that Hezbollah is a major political party in Lebanon holding 13 seats: https://en.wikipedia.org/wiki/Hezbollah_political_activities

They also have their own private army:

The Taif Agreement signed in October 1989 to end of the Lebanese civil war, besides other things, called for the disarmament of all national and non-national militias. Hezbollah was allowed to stay armed in its capacity as a "resistance force" rather than a militia

Lebanese issue is that it is being held hostage by a militia (Huzb Allah). No amount of money is going to help until these militias are disbanded and a national independent military is put into place.

Besides having a giant diaspora, this diaspora still has strong ties to the motherland and many of them are also very rich. Lebanon could then come back quickly and reach western levels of development and wealth.

Do you have experience in Lebanon? The only areas that are well managed (relatively speaking) are the ones run by Hezbollah.
