  We study the three-user interference channel where each transmitter has local
feedback of the signal from its targeted receiver. We show that in the
important case where the channel coefficients are static, exact alignment can
be achieved over two time slots using linear schemes. This is in contrast with
the interference channel where no feedback is utilized, where it seems that
either an infinite number of channel extensions or infinite precision is
required for exact alignment. We also demonstrate, via simulations, that our
scheme significantly outperforms time-sharing even at finite SNR.
