During the cold war, it could have been seen as a means to prepare for a first strike, and now I can see it being useful in Pakistan and India in a worst-case scenario.
Again, testing it as a possible weapon (I use the term loosely) to prevent or delay an enemy nuclear launch wouldn't really be applicable to other nuclear launch sites. It's not as though the Russians were also using Minuteman missiles. Different technology was at play, and I assure you that there isn't a common "off-switch" on all nuclear launch facilities.
Besides, could you imagine that conversation?
"Sir, we are going to test the device that will temporarily deactivate nuclear weapons in a certain radius."
"How can you test it?!"
"Sir, we will just try it on one of our own missiles."
"But, don't we need to know how to shut down enemy missiles?"
"Er... anyway... we need a distraction, sir."
"Why's that?"
"Sir, we can't tell the people in charge of operating the missile!"
"Um, why?"
"Sir... this is a secret."
"Wait, wouldn't we want to advertise the fact that we are developing a way to prevent the enemy from launching missiles? Anyway, what kind of distraction?"
"Sir, I propose a disc in the sky of some sort."
"Hmm... a disc, huh? How will that distract the people inside?"
"Sir! It won't! Isn't that brilliant?!"
"I don't follow."
"Well, sir, the guards will see our flying disc, and report it to the people inside. Then we can test our device on our own missiles. We'll do it again next week."
"Well, before you plan for next week, let's see how the debriefing goes."
"Sir... there won't be any debriefing... it's a seeeeeeecret!"
EDIT: And thus, the top secret government program to shut down our own nuclear missiles for a bit while distracting the guards outside with balloon begins!
EDIT PART 2: Sorry, Nismar, I'm not trying to be rude. I'm trying to explain to you why I can't imagine the government collusion theory being very workable. Maybe it's just lack of imagination on my part.
