Limited - hopefully! - nuclear war. God Help Us!
I feel that Nuclear war is a strong possibility.
I believe it will be a limited nuclear war insomuch as there will be nukes dropped somewhere in the middle east, and al Qaeda and company will drop a suitcase nuke in a major US city. After the devastation is broadcast across the globe, there will be calls for a “cease fire,” but brokering it will be more impossible than an Israeli-Palestinian border agreement.
