I think in this particular circumstance, it might be worth the investment. This is because, if we get the textbooks, it means the Islamists won’t choose the textbooks, and every girl who gets educated will be one more woman that will not want her daughter reduced to farm-animal status by Islamists.
For all his faults, Saddam was a firm believer in a secular society, and was a lot closer to our point of view than the Mullahs in Iran. Had he put more time, effort and energy into keeping Iraq together, instead of being a dumbass and invading Kuwait, he would very likely still be in power and treated like we treat the other tyrants in the region.
In any event, the Iraqis are still leaps and bounds more urbane than a lot of the Arabs in the region, and if we can keep them sedate instead of Islamist, it will prevent a lot of heartburn down the road.
Which part of “we are broke” are you having the most trouble with?
