Even if successful, China Show would have delivered a mere 15 tons (the approximate max cargo weight of a zeppelin for a journey that long) of supplies. That would work out to about 60-120 rounds of 8mm Mauser per soldier, if it had been purely small arm ammo. As much as that, and the other benefits from scavenging the zeppelin for other parts, would have been helpful it would have been mostly symbolic. A single cargo ship would have brought hundreds or thousands of tons of supplies (if the Germans had retained control of the sea or, indeed, the Tanzanian coast) to provide a frame of reference.

Further, the only benefit Germany ever gained (or indeed ever could have gained) was a morale boost. The Allied forces were almost exclusively Kenyan natives (who the British would never have deployed to Europe) and South African (who had already refused to deploy outside of their regional territory). Only a small contingent of Indian forces ever deployed to the east African theater, and the British made scarce use of their Indian forces outside of the Middle East theater as it was. Lettow-Vorbeck, in the end, accomplished very little in reality given what we know today.

China Show was a pr stunt, and an interesting study, but of no strategic value.
