Marhaba.
I live in Lebanon, Aley district. Israeli airstrike targets are at proximity of my location. Beirut, and particularly Dahieh, is completely visible from my balcony. There are also refugees sheltered in my town.
Other things to know about me: I am a leftist, and a legal and political writer.
P.S. I will answer anything (as it is with AMA posts), not only issues pertaining to the recent events.
Since the 90's the two biggest sunni and druze parties—respectively, Future Movement and the Progressive Socialist Party—were anti-syrian and anti-iranian. FM had for the longest time tacit Saudi support. In 2008, Hezbollah clashed with both FM and PSP over the former's telecommunication systems.
Today, FM is inactive after its leader resigned from the premiership in 2019. There is a void in sunni politics, and they are divided among themselves but the populace is generally supportive of the resistance. As for the PSP, its position is a bit ambiguous and its leader seems to be on good terms with Hezbollah; shocking considering that most druze are adamantly opposed to Hezbollah and Iran.
Christians are divided on the issue. Some parties are pro-iranian while others are not. Shias were also divided along those lines historically but they managed to put aside their differences.
