What, like charismatic, independent Sean O'Keefe,
who argued rather forcefully with his boss and
his boss' other staff that NASA was important,
enough so that his agency was the single non-DOD
agency which got funding boosts in the last
couple of years?

That has not been true since the early 1990s
at best.

Atlas: current generation uses different tanks,
a new Russian engine derived from one that has
only ever flown on non-missile vehicles (RD-170
was designed for Zenit and the associated
Energia booster). Upper stages are RL-10
based Centaurs with no missile heritage,
though the RL-10 came out of some turbopump
work for the liquid hydrogen precursor concept
to the SR-71, which at least is miliary.

Delta: current generation uses different
tanks, a new US engine which is completely
new, burns LOX/LH2, and has no design heritage
with missile components for 30+ years,
and an upper stage using the RL-10.

Pegasus: Commercially developed, using custom
developed solid motors with no significant
design heritage to weapons other than size.

Taurus: Uses Castor 120 first stage, which is
a civilianized Peacekeeper first stage, but the
rest of the vehicle is Pegasus derived.

SpaceX Falcon-1 and V: zero missile heritage.
New tanks, on new tank concepts, from a brand
new company with no prior military work.
Motors are derived from an experimental
clean *** design done by NASA for lower
cost liquid rocket motors.

SeaLaunch: Uses a Zenit model, which is an all new
tankage and a motor purpose developed for it,
with no military system design heritage per se
as far as I know.

Zenit: see above.

Soyuz: This, in deed, was once a ICBM, though without
the current second stage.

Dnepr: A decommissioned SS-18 missile.

Arianne 5: A new clean *** design, using LOX/LH2,
with no design heritage with missiles.

H-II: A new clean *** design, using LOX/LH2, with no
design heritage with missiles.

They are not optimal for launching payloads
into orbit because of their high cost.
Cost and reliability are the only criteria
that matter.
