Theoretical question.

Say Russia went bezerk and decided to unilaterally de-orbit the station,
and gave USA limited warning. (and assuming Russia could re-orient
station such that its Porgress woudl be able to slow down station).

Would the quickest disconnect be between Zaria and PMA1, or the CBM
attachment of PMA1 to Unity? (I assume CBM is more likely to still be
working since they would add more recent CBM motors ?)

Between US and Russian segments, are there only electrical/data
connections or are there also some ammonia for cooling?

Say PMA1 is split from CBM hatch on Unity, leaving external electrical
connections. Would Canadarm have enough power to push Zarya away and
force electrical cables to snap? (Or could DEXTRE be used to sever
those cables, or absolutely require EVA? )

Assuming separation had been accomplished, would CMGs automatically
adapt to new centre of gravity, need new parameters, or would their
location at one end of station make they almost useless for attitude
control?

Assuming for a minute that Alenia built another MPLM and that SpaceX
would fit in tanks and engines for reboost and it is mated to aft hatch
on Unity. Works fine and dandy, how how would it be refueled?

In the early days of ISS when they were planning on a US reboost module,
had they worked out how it would be refueled?

With today's tech, would a reboost engine still be hydrazine, or would
SpaceX pitch methane/LOX engines ?
