While the Trump admin is idiotic, the Iran conflict is just a repeat of the events in the later half of the 20th century.

Russia has exhausted itself trying to obtain some paltry mineral resources.

China is highly aggressive and will continue to expand into neighboring countries like they have already been doing, they're the most likely cause of a widespread global conflict, but judging by their incompetent handling of Venezuela, Cuba, and Iran as well as their rapidly declining population due to irresponsible governing (they executed or exiled most of the social policy experts a century ago and put a missile defense scientist in charge of the bureau that tracks population trends resulting in the One Child Policy) I doubt they will be confident about any longterm wars. Still, they constructed a mostly underground military city near beijing 10x the size of the pentagon, so they're definitely planning something.

Fact of the matter is, for all competent leadership, war is less efficient means to obtain things you want than trade. War has become too expensive in the 21st century. Only idiots wage war.
