For the premillenialist, the present evil could not be "the little while", since the millenium is yet future.A question for Padion, or others: Could the deception of the nations which we currently see be related to the "little while" that Satan is loosed near the end of the millenium?
For the amillenialist, we are still in the "millenium" (figure of speech) the period of time signified by "the thousand years" of Revelation.
I suppose the postmillenialist might consider the possibility that we are living in "the little while" since he is expecting Christ to return after the millenium.
