While I don't have any war experience, I might still be useful if the leftists mount a coup against the legitimate government, and impose a tyrannical socialist dictatorship.
Unless there is a complete breakdown of law and order, there will still be lawyers in the new regime. And a lawyer is in a very good position to pretend to work on behalf of the ruling power, while secretly maintaining contact with the resistance. As a lawyer, I can visit with resistance leaders who are jailed, and if there is still such a thing as attorney/client privilege, I can communicate with these leaders and act as a courier between them and their followers on the outside. I have never worked in intelligence, but I have some familiarity with standard covert methods, like dead drops, code books, and secret communication methods. I would have to terminate all open expression of my opposition to the ruling power, and may even have to feign support of it in order to establish an effective cover as a loyal member of society.
Of course, all would be lost if the secret police got archives of this political forum, and learned my true loyalties, so I would urge the administrators to destroy all their data before the socialist regime establishes control.
The most probable event, in the event of a radical leftist takeover of our nation, is that I would be on the list of people to be arrested on the very first day, and I would be shot very quickly after my apprehension. I have always known that about myself, that I would be one of the first to be shot, and it is the price I would pay for a lifetime of speaking out without fear about my opposition to the entire leftist agenda of all-powerful government, seizing of private property, elimination of religious liberties, abortion and euthanasia, and all the rest.
I do not fear the possibility of death, because I am at peace with who I am and what I have done and I have no regrets. I have lived a good life, and I was a good father, and I was always honest in my dealings with my clients and peers, so I am at peace. I may spend some time in purgatory, but I would eventually be in heaven. From there, I think God would assign me new tasks to continue the fight against the forces of evil. I do not believe that heaven is a resting place, I think every soul who goes there is very busy in this struggle between good and evil that has lasted since the beginning of time, and will not end until the Second Coming of Christ.
