Bribes from AI

I would really like to see this feature!
I mean... if some AI offers me the right goods i would consider attacking his foe... right now there is just no gain doing it... AI ask you to go to war for free - mmm i dont think so. I think of it as a giant setback in game. It should be as the other trade proposals - they should be able to propose you stuff for going to war just like the player can offer bribe to AI for war. Especially when they ask me to go to war every 3 or 4 turns

Previous versions of Civ had that.
It lead to the human accepting the bribes against distant targets but doing nothing.

well... everything has its flaws i guess. Never though of that downside, but it also apply on AI accepting bribes to attack someone and then doing nothing
