I like to take a national defense stance for healthcare, and it deffo catches people flat-footed.

Providing healthcare to the citizens is how we keep our population healthy enough to repel an invasion. There's that famous apocryphal quote about how the Japanese didn't invade in WWII because we have a gun behind every blade of grass and they were afraid of our fighting spirit. These days, the rest of the world sees us as fat and lazy, so we're making ourselves into sitting ducks by refusing public-option healthcare. We couldn't do a draft now, we're too unhealthy.
