If any event has pushed us closer to WW3 it is the US's decision to preemptively attack Iran.

Based on what outcome? The regime is still intact, if not stronger. They are likely more resolute in wanting a nuclear weapon, as we almost certainly wouldn't have attacked them if they had one. They have validated their control over the Straight of Hormuz and it's impact on our economy.
That's a propaganda line. Iran has lost most of its capacity to make war, but it can still harass.
The money is also not as relevant as people think. The amount of money is largely political fluff, not much in the way of serious economic impact in a $32 trillion economy.
Iraq was never really about WMDs. WMDs were a surface political mechanism to achieve the aims, which were different. If you look at all the individual events that transpired before then it was clear something had to be done, but it wasn't a neat one liner that's easy to rally people around like WMDs.
