> So Iran colonized Lebanon
They haven't "colonised" anything, and, at best, it's disingenuous to describe training a resistance group as such.
> It operates as a parallel state inside Lebanon (own military, telecoms, social services, foreign policy), displacing Lebanese sovereignty in the south and Bekaa.
To claim the "officially recognised" Lebanese state is sovereign is utterly ridiculous! They are stooges, tasked with sitting back and doing nothing while Israel carries out ethnic cleansing and genocide. An MI6 front (Westminster Foundation for Democracy) even has an office inside the Lebanese parliament.
Turns out that if you take over a country's government and continuously carry out appalling attrocities against it's people for decades, they will resist.
