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.
