Then there were other chassidim who said look, the Rebbe never lied to us. The Rebbe predicted things the seemed nuts, and they all came true, such as the outcome of the Gulf war on a global level, and hundreds or maybe thousands of personal accounts of the Rebbe’s ruach hakodesh.
So maybe it seems a bit illogical but why should we distrust what the Rebbe said now? Everything else came true, this will as well.
These are the Meshichistim.
