We consider a (2+1)-dimensional SU(N) lattice gauge theory in an axial gauge with the link field U1 set equal to one. The term in the Hamiltonian containing the square of the electric field in the 1-direction is nonlocal. Despite this nonlocality, we show that weak-coupling perturbation theory in this term gives a finite vacuum-energy density to second order, and suggest that this property holds to all orders. Heavy quarks are confined, the spectrum is gapped, and the spacelike Wilson loop has area decay.
