Why I have difficulty writing haiku

problem with haiku
definite article is
first casualty

next casualty
indefinite article
makes me sound little

like Japanese guard
in prison camp in movie
world war two movie

who for some reason
is speaking English (how? why?)
with staccato voice

or perhaps I am
po-faced guru on mountain
dispensing bromides:

crow flies at midnight
in front of luminous moon
affair ends badly

all because I am
in service to, at mercy
of, syllable count.
