AIs asking for you to join in war?

[Mr Justice]

ya gifting units is a good idea. i often gift missionaries. buts thats just to get rid of em.
it would be good addition to diplomacy if units which u own and were within the cultral borders of the AI to appear on the diplomacy screen, would require that open borders be signed first.

i rarely go to war when asked, i'll take the diplomacy hit.

There needs to be more options than just yes or no.

Gifting units, resources, money, techs to name a few.

And maybe the option of "Well if you would just hold off invading those guys, while I finish off these guys, then your on!"
