Because the original formation of IDAR goes back to the Mars Germans getting out of their original moon base lease, in which they leased the property from the Draco in order to build their first moon base. In order to get out of that lease, they had to do a couple of things. They had to provide some troops to the Draco for use where and when they needed them, which was what? The IDAR fleets were. And they also had to find another tenant. That other tenant that they found was the Cabal. The rest of Earth's SSP programs. They're the ones who took over the Mars Germans' original moon base.
