I don't know how big an army Nepal thinks it needs.
The CPN look like they are going to be able to form a government with an absolute majority, without coalition. If the Army dont think they can work with their former enemies it does not bode well with them taking orders from those same former enemies as their political masters. Might they not have a more reliable army if they keep the 32,500 that were on their side and disband the Kings army that were against them - or make them park rangers.
