If the power associated with
an EM pulse is not in the pulse, where is it?

According to definition, the 'effect' of power is something which can be
realized at a place where energy either is being transferred from, or
transferred to. The amount of effect is proportional to the rate at
which energy is transfered. But power is not the thing which is being
transferred from one place to another. Often times though we want to
know the rate at which energy is being transferred to or from one place
to another, and there are mechanisms we can use to measure things that
manifest themselves in proportion to that quantity. But some folks
forget that it's just a tool for making accurate predictions about
things, and start to believe some odd things about the behavior of
nature. One must be careful not to mistake a physical quantity for a
physical entity.
