They've colonized the whole region with their proxies, from Lebanon to Yemen to Iraq, previously Syria which they attacked with Hezbollah to support the Russia-backed Assad. About 1 million dead people from all this proxy warfare. Lebanon in particular wants to be a normal liberal democracy but their proxy militia assassinates any politician who stands in their way.
Colonized? Are Hezbollah not Lebanese? Were assadists not Syrian? (assadists invited Hezbollah) And how did Hezbollah come to be?
I think you're simplifying quite a bit. And you're also omitting Israel and other near east countries or groups as a proxies of USA, simply by avoiding a clear and sensible non-discriminatory definition of what a proxy is.
Eg. USA's Israel "proxy" crucified (literally) a "Palestinian Christian poet, advocate of non-violence and PLO spokesman" in Lebanon and executed a random woman who stood in the way of their operation. This is one of hundreds a lot of the time political assasinations IL did all around the world.
Also Iraq attacked Iran during Iranian revolution in the past. You can hardly call Iraq a victim of Iranian proxy warfare.
You can't ignore history or the long-term USA and Russian meddling in the region.
Seems like significant subset of what you call proxies are locals who formed a group and tighter (Hezbollah) or very loose and inconsequential (Hamas) alliances with Iran, in response to either beligerent occupation/aggression or invasions by some other groups like Israel, Iraq, Saudis - basically in response to wars fought over land and resources.
