This presupposes that the AGI community is, on average, homogenous across the world and would behave accordingly. What if the political climates, traditions and culture make certain (powerful) countries less likely to be fearful given their own AGI pool?

In otherwords, if country A distrusts their staff more than country B due to political/economic/cultural factors, country A would be behind in the AGI arms race, which would lead to the "even if I hold onto my morals, we're still heading into the abyss" attitude. I could see organizations or governments rationalizing against the community moral pledge in this way by highlighting the futility of slowing down the research.
