is there a place i can go to find out who is at war with whom and who is allied with whom?
cabal wars
Yeah, it is called Syndicate 
Or at least an alliance with them 
A current list of alliances and vendettas would be information privy to those in game that have access to it. At least this is how I have always treated it.
There are some presumptions you can make however regarding vendetta's. If you read the history behind the cabals you find some obvious eternal conflicts.
Savant vs. Warmaster, very rarely are these two ever in anything other than a vendetta. I think maybe once in th elast 5 - 6 years.
Nexus vs Knight, this is a duh...The eternal cookie cutter good vs evil. This has never stopped.
Tribunal vs Watcher, freedom vs tyranny. Development vs nature, I dont recall ever seeing these guys (since watchers inception) ever being anything but a Vendetta.
Syndicate historically does what they will, and I doubt they would tell you who they are allied with..
Herald tends to fluctuate between a few of the often times not so evil cabals.
Also some of the Cabals can behave in a bi-partisan manner, Warmaster and Savant allow all aligns and can at times be more evil or more good depending on who is in them. This will at times influence the Nexus and Knight conflict as the less align restricted cabals swing alliances and vendettas depending on their makeup.
Savant, Nexus, Syndicate, and even Knight tend to have qraces at times. Remember anything (even an Avatar) is considered blasphemy by Watchers. I think this is why the Watchers seem to get beat up a lot. Since they will attack despite current alliance any undead, demon, Avatar etc. in any cabal they are allied with. The cabal cant let this happen so they slash alliances and sometimes go to vendetta's.
That should cover the gist of things..

i'm talking about the current wars....
nobody will tell you on the forums here
though if you use what I listed you will probably be 90% accurate with a few fuzzy spots.
You'll find out who the cabal is fighting when you join them :-)
FYI - some vendetta's are always in place.
