Theory about JD’s dad

So I was watching the musical again (this is my third time btw) and I noticed something about JD's dad: he really seems to like to blow things up. That got me thinking, could he have served in the Vietnam War?

Imo, it would make perfect sense. He seems to be middle aged (maybe in his mid 40) by the time of the musical, meaning that he could've been roughly 20 to 30 years old during the peak of the war, which was in the early 70s.

While in the war, he could've learned about explosives and once the war ended, he could've started his demolition company. This could also potentially explain his weird behavior given that many veterans suffer from some sort of trauma related to the war.

This is just me thinking off the top of my head and I just wanted to share this. Let me know what you think.
