Depends whether you expect this conflict to continue.

If these are the opening salvos of WW3 or even just a protracted regional Mideast war, yes you should get the EV. Experience in WW2 was that it became impossible to get petrol & diesel at any price. Supply lines would often be disrupted, and what petroleum products were available were usually allocated to the military.

If tensions die down after the midterms and eventually a peace accord or even stalemate is reached, you're looking at about 2-3 years of current prices. It'll take time to rebuild production in most Middle Eastern countries, many of which have had large oilfields, pipelines, and tanker loading facilities destroyed. You'll have to run the financials yourself of how much an EV costs, how much life you have left in your existing vehicle, and what local gas and electricity costs are, but I believe most EVs don't pencil out economically if it's just 2-3 years of current gas prices.

A third option is that everybody else (notably China and India) switches to EVs. If this happens gas will go down in price through reduced competition for it, and so you may be able to enjoy cheap gas for the remainder of your vehicle's lifetime. But note that in this scenario, you probably want to switch to an EV yourself, as eventually parts, repairs, and infrastructure for gas cars will become impossible to find.

Note that it is now outside of the control of the POTUS or U.S. military whether this conflict continues. They can prolong it, but they can't stop it. Recent aggression has been driven by Iran and its proxies, who are demonstrating that there is nothing the U.S. can do about it.

Well the US could put boots on the ground, launch nukes, do any number of crazy things. And sadly with the current administration it seems everything is on the table.
