The devastation is caused by ruining the electronics. They don't just go off-line and need to be rebooted. The EMP fries them.

No. a Briefcase Nuke would not produce an EMP. It would just kill lots of people in a small area.
EMP attacks are produced by high altitude detonations particularly if they are going to affect the entire nation.
EMP (Electromagnetic Pulse) Bombs An electromagnetic pulse EMP is a byproduct of detonating an atomic bomb above the Earth’s atmosphere. When a nuclear weapon is detonated in space, the gamma rays emitted trigger a massive electrical disturbance in the upper atmosphere. Moving at the speed of light,
this overload will short out all electrical equipment, power grids and delicate electronics on the Earth’s surface. In fact, it would take only one to three weapons exploding above the continental United States to wipe out our entire grid and transportation network. It might take years to recover from, if ever.
