Between the Clinton Regime, the Obama / Biden Regime, the Pelousy Regime, ET AL, it is doubtful that anything is safe. There is some good news in that backward societies and tyrants do not engender a great deal of entrepreneurship and risk/experimentation. They might be able to to use things for a short time, but when things break down and need regular care, they fail. I remember several actions in the Middle East. The Air Force worked 24/7 to keep jet aircraft, large and small, in the air.
