Third attempt is looking very promising so far. Rather than attempt to intimidate the enemy out of advancing their rockets, I have been feeding them infantry in the south. Since rockets cannot move and fire on the same turn, this means they are stuck defending against an endless stream of suicide attacks across the mountains. Hopefully, this will paralyze the enemy long enough for me to build up my forces in the north.
Well, everything went according to plan, and I managed to keep the enemy's rockets occupied until I could push the rest of their forces out of the north. Unfortunately, due to the level-up system in the game, this now means the enemy has a stack of super-powered rockets. I've built my own pile of rockets, and for the last 15 turns or so we've had a stalemate, trading control of the pass leading to the enemy base and turning it into an unpassable valley of death.
