Precisely this.
I'd argue that ALL wars are foundationally resource wars - in contrast to the limited scope of what most historians would point to as "resource conflicts" that are more acute conflicts.
Iran-Iraq is a perfect example of this
1. Proto-states of Iraq and Iran claimed monopoly access to the Shatt Al Arab [1] river starting 3000 years ago (the original resource conflict)
2. These proto-states eventually signed a treaty in 1937
3. Iran stopped abiding by the 1937 treaty in 1969 - because they wanted fewer constraints on their use of the resource
4. Iraq and Iran then agreed to the Treaty of Algiers in 1975
5. Iraq kicked off the first derivative conflict by invading Iran - because they wanted fewer constraints on their use of the resource - this time funded by the Kuwaitis
6. The second derivative conflict started when Iraq invaded Kuwait to cancel the debt it had with Kuwait leading to the....
7. Third derivative conflict called Desert Storm
The desire for greedy monopolization of resources to the exclusion of others - based on a fear of persistent and forever scarcity is the ACTUAL root problem. There's plenty of river to go around as was proven time again with treaties, but greedy avarice rules the day and the entirety of the Levant has handicapped itself with these repeated insane wars based on fake scarcity.
