Baha'is are to seek non-combatant service or what's called a IAO classification in selective service if drafted... otherwise we're supposed to follow orders.
Baha'is are allowed to defend themselves if attacked when there are no law authorities there to call upon.
Baha'is seek world peace through international bodies and believe peace can be attained through a representative world government.. this was a principle teaching of Baha'u'llah in the 1870's and when He was imprisoned and in exile He addressed the world leaders through Tablets urging them to set up a world parliament to reduce armaments and establish peace!
