Your son joining the marines may be a very bad idea.

He is going to serve the marines. But who do the marines serve?

The brainwashed nationalist in you who was brainwashed reciting the pledge of allegiance to the flag and national anthem devotion might say it is to serve "the people."

I caution you to be more realist, and honest, and realize that our military, including the marines, are merely mercenaries for bad people.

Your son becoming a lowly paid mercenary for a corrupt government is not something I would encourage.
