I actually don't include treaties that "don't count" and alliances that "don't matter". You'd be surprised at how many treaties count.
And there is a very clear "north" and "south" right now. But each of those regions is its own compartmentalized mess. Down south you have SF/XX/Chestnut/Aftermath/Sentinel/NpO; no alliance in that mass has initiated a major war in recent memory, only followed the lead of some other provocateur or defended. Also, four blocs overlap one another. Up north you have DH/C&G/Aztec/DR/NPO/TOP/MI6, wherein most component parts of that mess hate most of the other component parts, such that nothing in it can readily project power at present. There are some ODPs connecting those two groups that played a role in the last war but are diminished in the present atmosphere.
Amusingly enough, TIO might be one of the better connected alliances right now, with treaties leading to C&G (GATO), DR (IRON, Argent), NPO (sphere unto itself), and Aztec (-->LOSS-->DT). No one alliance down south carries connections vital to the rest of the group--there are a zillion redundant treaties, possibly because nobody up north wants a thing to do with them.
