For the OPEC+ oil cartel, wars are business as usual. In fact, wars among its own members are pretty normal, too.
Iran and Iraq remained OPEC allies-cum-rivals during their 1980-1988 war. The oil ministers of Iraq and Kuwait sat down at the same table even after Baghdad invaded its neighbor in 1990. And today Saudi Arabia and Iran talk about oil even when Riyadh says that Tehran sponsors the Yemeni Houthis that are throwing missiles at the kingdom.
