Well, personally, I'm looking forward to a little street fornication... but...
By trade, I'm a logistics planner. Amongst my duties is determining the infrastructure necessary to sustain military operations in a certain location, putting it in place, and at then end, tearing it back down.
Based on what I know about doing this, it would be impossible to take the United States from it's current state to "animalistic street fornication" in nine years. Nuclear strikes couldn't accomplish that... no matter what you heard on Coast to Coast AM.
Here's a worst-case scenario. Total thermonuclear war with an equivalent nuclear power... say China. (Iran lobbing one pissant missile at DC would be tragic and life-changing, but it wouldn't collapse the United States.) All levels of government, local, state and federal have survival plans. It's not going to be Mad Max ten minutes after the bomb hits. Master Blaster will NOT be running Bartertown. Government services will be limited to essentials; public safety, utility maintenance, infrastructure reconstitution. The biggest loss of US Gov't functionality will likely be the welfare system. No more farm subsidies, social security and SSI, medicare/medicaid payments would be being made.
So, what I ask you, "future event viewer", is to be specific. What did you view that gave you this impression? Not your feelings, or what you sensed. Something along the lines of, "In the early 20-teens, I saw Lindsay Lohan escape from prison and go on a massive crime spree, culminating in the firebombing of Watts Towers."
