No!

The widows of two combat veterans sued the government Monday for not allowing Wiccan symbols on their husbands' military headstones.
The U.S. Department of Veterans Affairs allows military families to choose any of 38 authorized headstone images. The list includes commonly recognized symbols for Christianity, Buddhism, Islam and Judaism, as well as those for smaller religions such as Sufism Reoriented, Eckiankar and the Japanese faith Seicho-No-Ie.
The Wiccan pentacle, a five-pointed star surrounded by a circle, is not on the list, an omission that the widows say is unconstitutional.[via CNN]
