The meaning of an upside-down peace sign tattoo depends on the intention of the individual wearing the tattoo. Since upside-down symbols are often used to express the opposite of something, the intended meaning could be anti-peace or pro-war. It could also be seen as a broken cross, an anti-Christian symbol.
On the other side of the argument, there are some who believe the peace symbol was incorrectly constructed from the beginning and that the current version is wrong. They believe the peace sign was meant to symbolize the tree of life and that the current version must be inverted to properly communicate this idea. However, this idea conflicts with the official history, which states that the peace sign is a combination of the semaphore signals for the letters "N" and "D," standing for "nuclear disarmament."
