The United States is the world's totally dominant military power, and
the revolution in military affairs (RMA), with the introduction of new
sophisticated information technologies, also has the potential for ra
dically expanding U.S. military superiority. But as this article demon
strates, U.S. defence policy is at the same time beleaguered with seve
ral underlying structural problems. First, the widespread American pol
itical reluctance against international military engagements threatens
to undermine the U.S. international military role. Second, unless the
growing mismatch between the use of resources on current operations a
nd on necessary modernisation is corrected, it will seriously affect t
he long-term U.S. military capability. In addition the U.S. defence po
licy process contains several fundamental political-military-bureaucra
tic barriers against necessary changes in U.S. military doctrine and s
trategy.
