Are EVs truly more optimal than legacy internal combustion technology?

I pose only a question here, although I will probably spend a bit of time trying to answer it, from whatever reliable information I can find. 

Which is more optimal, internal combustion motor vehicles or electric vehicles if you take it as a given that to consider the true efficiency of each, you need to take into account not only the onboard vehicle efficiency, but the environmental and financial cost of producing and delivering refined fossil fuel, and the environmental effects and financial cost of operating the vehicles over an arbitrarily equivalent "lifetime" (which may ignore superior longevity of EV systems)(and this would have to include impact on climate, which is not zero EVs)?

I'm pretty sure this exercise will show that EVs are greatly better in all important respects, even if you burden them in your weighing of effect with the cost of building out new charging infrastructure. Since we probably aren't considering the very costly geopolitical actions of governments to ensure access to oil (or rare earth metals for that matter), it seems a little unfair to burden the EV paradigm shift with the economic costs of the disruption to legacy internal combustion industry. Particularly since most technological changes intended to reduce the impact on climate are similarly disruptive, and even the mere continued use of ICE technology has many negative and disruptive effects on civilization.
