We study the effect of drag induced by the Galactic hot halo on the twoneutral hydrogen (HI) cloud complexes associated with the Large and SmallMagellanic Clouds: the Magellanic Stream (MS) and the Leading Arm (LA). Inparticular, we adopt the numerical models of previous studies and re-simulatethe tidal formation of the MS and LA with the inclusion of a drag term. We findthat the drag has three effects which, although model-dependent, may bring thetidal formation scenario into better agreement with observations: correctingthe LA kinematics, reproducing the MS column density gradient, and enhancingthe formation of MS bifurcation. We furthermore propose a two-stage mechanismby which the bifurcation forms. In general, the inclusion of drag has a varietyof both positive and negative effects on the global properties of the MS andLA, including their on-sky positions, kinematics, radial distances, and columndensities. We also provide an argument which suggests that ram pressurestripping and tidal stripping are mutually exclusive candidates for theformation of the MS and LA.
