Yeah, there have been many errors and misinterpretations when it comes to the US and Russia thinking they're being attacked. This one's probably the most...humbling? I don't know:
In June of 1980, the warning system located at the SAC command post near Omaha, Nebraska, gave a signal of an incoming submarine-launched ballistic missile attack. All the B-52 bomber crews on duty received the command to take their places and turn on the engines. The airborne command post was readied for takeoff as well. Only three minutes later did it become clear that it was a false alarm, and an all-clear signal sounded. Subsequent investigation of the incident revealed that the false alarm had been caused by the malfunctioning of a 50-cent computer microchip of the early warning system.

So, yeah. The possibility of going, "They're attacking us, fire back," which makes the other side go, "They're attacking us, fire back," is one that's pretty frightening and very real.
In the mid 1960's(never bothered checking the date because i drive by the fenced area every day on my way into town) a bomber crashed in the countryside near my home(im located at an airbase flightline); it was carrying 2 nuclear weapons - one was recovered, but due to the force of the impact of the bomber as it hit the ground, the second bomb could not be recovered easily enough, and since you cant hit a nuke with a hammer to make it go off, they simply left it buried 200+ ft under the ground. However reports were released in 1984 that sited the nuclear weapon which was left there had reached stage 4 of a 5 stage arming sequence. since then a security perimeter fence has been erected and surveillence is constant. i doubt you could get out of your car and walk to the fence in the middle of the field before you were intercepted by black trailblazer SS's.
The Soviet Premiere during the late 1970's(im not going to attempt a spelling of his name, i get them wrong all the time anyway) was also confronted by a similar conundrum. the Defense Computers which monitored for incoming nuclear attacks reported birds in the air heading towards the USSR. All available information confirmed this; so, the premier was faced with a decision: Retaliate, destroying the world, or wait and see if it was a false alarm. he decided to ignore the computer warning...and it turns out, the computer was in error.
also in the 1970's a B52 crashed in southern spain, laden with nuclear weapons. although the bombs didnt go off, it forced the US to cancel their nuclear delivery training excersises due to protest from Spain's Government and other non-nuclear powers.
