I think it's a matter of how important the WoL is to the people in general, and if they would riot should he (using the Derplander as the default for gender considerations here) be put up on the chopping block.
However, and it's been a while since I saw the events of 2.55, I think at that point in the story is when the WoL is supposedly at his "lowest." Which could also means folks may not think as highly of him since they could be buying into Teledji's claims. So, less likely there would be riots against the execution. They might still happen, sure, but it would've been far less likely.
More of a "he used to be so great, then he killed the Sultana!" sort of situation.
So, I don't think there would've been an Eorzean war over the WoL being killed. Outcries and spots of outrage, sure, but I don't think there would've been a war over it. Then again, that isn't what happened, so we will never know for certain.
