To stop his attacks you can either:
Ask him to stop - some people are nice, this might work.
Ask the host of his alliance to make their alliances status friendly with yours
Use a True Agreement - only works for 12 hours and can't be used while under attack
Teleport your city - he can't attack what he can't find.

To be able to attack him -
Have your alliance take his alliance off of Friendly status
Quit your alliance.
oh wow, I totally missed that. I assumed because of this guys outrage that they were both friendly towards each other. if they are not friendly to you, then you need to alter your side's own feelings towards them.
