Yes, absolutely, it’s just a deeply complex scenario domestically.
At the end of the civil war the peace deal baked in a certain amount of political representation from each sectarian group (Sunni, Shia, Christian and Druze) which was necessary to stop the fighting, but also perpetuated sectarian identity as a primary driver of politics.
On top of that you have Hezbollah, created and funded by Iran and operating as a participant in the political institutions, but also as a shadow state and military force.
The legitimate Lebanese military receives aid from the US and France but is actually weaker than Hezbollah. Political corruption is endemic, the economy is buggered and 1/4 of the total population is Syrian refugees which puts even more stress on the system.
All of the major powers in the region compete for political influence and encourage corruption to enable that, destabilising the country by design.
That’s a grossly simplified summary but gives a flavour of the complexity.
