Iran war & oil and gas stocks: conservative investor what to do?

It seems quite likely President Trump will escalate the Iran war, find he still can't 'get the job done', and then who knows what. In this context, what should conservative investors do with their oil and gas stocks? I was thinking to dump stocks like XOM (nothing specifically for or against Exxon) in 5-10 days, taking the profits from the ongoing and probably increasingly severe post-failed-escalation oil price surge. Beyond a week or so, I worry as an investor (as a human I'd love to see it) that Trump will throw in the towel and oil prices will drop significantly. But what's wrong with holding for several or many more months and enjoying the impact of historically high energy prices? What's possibly wrong is the world economy seems very likely to fall off from the damage the war has done and will do, which likely (?) means big decrease in demand for energy. Any relevant thoughts much appreciated.
