Wish we wouldn´t be agreeing on the AI being short-sighted, not to say daft at times,but we are

Guess the game has it´s limitations,yet I don´t think this is really AI´s fault but rather that of Firaxis,sorry peeps

The way I see it,it´s a minor tweak in programming of the AI that would do the job,Persia was an island not too far east of India,but France was on the other side of the map,like I said had tech superiority,aka battleships, carriers and loads of subs,there was simply no way France (with ironclads)would get any transport over the sea safely,the same goes more or less for Persia,their cause was doomed from the very beginning,and India was most stupid not taking this into account. It really is time for MP,but a tweak in AI programming would help till then,have read on other threads that the AI tends to count numbers instead of how advanced a civ´s units are,this should be changed for one,next thing would be to change AI respecting friendly ties to other nations,not always but it should take it into account,they had good relations to Persia, but also to me,yet it was France who pulled in India,senseless.Last tweak they really could add would be to give the AI a sort of strategic idea;
(possible) more/less powerful,advanced/inferior enemy~next door/far off;
(possible) ally close/far away;
conclusion: (no/)good idea.
It prolly is hard work programming AI,and I do respect that,but this really sounds simple to me,and possible.
Like you said the AI consists of short-sighted mercenaries.Shame.
Your example is just as messy as mine,this sounds to me like Russia being bought off considered the alliance with you as having been "broken" before the 20 turns ran out,objective: punish (treacherous) enemy for all eternity.
Another great example for AI stupidity.

How powerful were the nations in your game,btw?
Noticed that with the drafting of units too,not really upgrading is it,doh.Greece "upgraded" it´s lost riflemen by drafting recently discovered Infantry.
The Babylonians were catching up in science, they had remained in democracy and at peace while our continent was waging war.Babylon was second in ranking,our trade deals consisted not of money but dyes for furs,fair enough.Since they weren´t losing money to me in trade deals they did upgrade and changed their units pretty fast,more than a 100 cavalry shrunk to 50 instead they built 50 tanks, in around about 5 turns.Same goes for ~60canons->~50artillery and ~125riflemen-> ~115infantry. Think the upgrading of units is dependent on the money the Civ has either p/t or in general, often I make great profitable trade deals with rich nations who have several hundred gold,just to find them a few turns later ruined at zero gold.If a war adds to the household problem it will only get worse for this Civ.Well at least it builds it´s most advanced units. :crazyeyes
