What needs to be said here is how they deal with their allies. We had an alliance until very recently and they decided to break it just because we were "in their way". The alliance was broken with a one day notice. Pretty much immediately after this 24 hours the first attacks were incoming.
Now If we were talking about a NAP here this would be normal. However we had an alliance and alliances shouldn't be so easily broken. They should've thought about that we could get in their way before making an alliance with us.
Allies of S.O.H. should probably consider if this tribe is worth having as an ally. Sometime in the near future you might be "in their way". Besides, making alliances such as this one and breaking it a few weeks later shows me this tribe consists of, or atleast is being lead by, a bunch of noobs.
