"To overcome the pressure the society put an upward pressure, in the form of "Jana-Andolan II"." If I am not mistaken, your foreign object is (Prachanda) and water (Nepalese society) In the first line you say, the liquid (water) in turn applies upward pressure to the foreign object, which in your case is Prachanda. But Jana-Andolan II was not against Prachanda or Maoists; it was in fact against the KG or the monarchy. Monarchy was/is a part of the Nepalese society, so I guess, under the present scenario, you could refer to it as “unwanted water” that is displaced out of the container. But the problem I see with that analogy is while the king still has chance, at least theoretically(due to influence of the society--water), to come back to the power (ceremonial or otherwise), the displaced water cannot come back by itself (or due to water in the container) to the container again. Good thinking though!
