This is a bit simplistic. You need to detail the threat model, and
examine the value of the data being destroyed, the resources available
to potential attackers, and the amount of money and effort that
attackers are willing to spend on retrieving that data. Simply saying
"Good for US Military" is pretty much meaningless.
