How do I help a civ fight off sieges when they don't give open borders?

Don't gift the civ units - it will most likely suicide it the next turn.
Do not pay 50g for open border
Do not actually try to help the civ
Just let the be taken over, then swoop in and retake the city yourself.
Do not liberate the city.

Its not worth having AI friends in civ5.

I don't know, Research Agreements are pretty good.

Well it's nice to have weaker AI around for RAs, as has been mentioned.

But yeah, i do like waiting for the AI to weaken your nearby opponent, and then jumping in and taking the city before the other AI can

I was thinking that in this thread's scenario, a civ who is being destroyed in a war usually does not have the money for the RA. Even if it did; its refusing defensive help. Chances are it will not last the next thirty turns.

I would agree though, a weaker civ (with enough defensive military power), is nice to have around. You don't really need to be allies with them to continue getting the RA though. Its even easy to sign RA with enemies you just finished a war with.
