Part of the problem is that many FSOs today have never served in the military. I am a Vietnam vet with 8 years of military service and most of the FSOs I served with when I entered in 1972 had military service. They understood that their job could involve being exposed to dangerous situations. Since the end of WWII, more ambassadors have been killed in the line of duty than generals. Our embassies have been blown up around the globe and many US diplomats killed or injured. This sounds more like a political statement than anything else. Shame.
A class mate of mine was in Iran when it fell. He was a guest of the new regime until Nixon took office.
