25. If a war erupts in the ME, it will destroy oil exports and sink us
Into a Great Depression the likes of which no one has ever seen before. Oil is the lifeblood of the global economy, and an oil shock like that resulting from an Iran-Israel war would be devastating. Saudi Arabia and Iraq would probably get sucked in, and the entire region's oil exports would shut down.
I wouldn't be surprised if marshal law and rationing was declared, given how much we rely on oil for food, transportation, and importation of goods from overseas.
If you're really worried about a war like this, invest in land, seeds, gardening tools, a flock of chickens, and a cabinet of quality guns and ammo.
