Syria took nearly a decade. The US does not need outright military victory, it uses proxies and will at some point try to activate the Kurds or someone else.
If Iran is destabilized enough to undermine the Caspian Sea coalition and get the resources of Turkmenistan, that is also a victory. Unless the other theory is right and the US wants to export its resources first.
We don't know the exact plans, but the grand scheme is not Trump's idea. It goes back to the Bush era.
It can be true that Trump was the useful idiot who actually signed off the Iran plan, which another president may not have done. But the plans are there, including Caspian sea plans from decades ago.
