AviK there is NO machlokes that the dead know what is happening in the cemetery. The only machlokes is whether they know what is happening elsewhere.
Joseph, the reason the kneisia gedola opposed the partition plan was absolutely NOT that it’s assur to establish a state. The reason was that we have no right to agree to give away any part of the Land, even if in return we receive the rest of it. Better to have nothing and remain the rightful owners of everything than to accept that some parts are not ours. Moshiach will soon come and restore us to the whole land anyway, so the gain from a compromise is only short term. Only someone who doesn’t believe in Moshiach will say better to have something than nothing.
