Going by everything we've seen in the series, the 100 000 ninja couldn't possibly be fielded by the 5 nations + small nations. Even by generous standards, there's a fairly consistent factor of 10 missing. Meaning, either everything about the villages is only 1/10th of their capacity, or the Alliance was 10x bigger than they could be.

The simplest way to convey this is by considering replenishment. Imagine that 100 000 ninja is the limit, fielded by 5 nations. The mean starting age for a ninja is 10 (assumption), the mean retirement age (or death) is 50 (assumption). That means, 100 000 ninja have to be trained over the course of 40 years, by 5 nations. 20K ninja each, or 500 per year per village. Clearly, very clearly, the Academy doesn't do that. The Academy doesn't look much bigger than my local school, and that did around 30-40 students per year. Even accounting for shorter tracks (e.g. a 2-year course in stead of an 8-year course), smaller villages being included etc, it doesn't add up and we're stuck with a factor of 10 missing. And that doesn't even begin to adress my initial assumptions, since i don't think we've seen many Ninja retire in the first place.

He knew the uchiha were planning a coup but he wanted a reason to kill them thus Itachi was manipulated Itachi was the spy that told them about the coup in the first place. There had been Uchiha restlessness since the very inception of the village, hence why Tobirama made them police in the first place.
