Hit the nail on the head there Syruss... Also Anyone outside your tribe is an enemy and unless you intend on joining into one tribe at some point, alliances are simply temporary agreements made by two tribes that are headed in directions in which both are advantaged by the other's existence. As soon as the situation changes whereby one tribe no longer finds the other's existence to benefit them or is threatened by the other tribe, an alliances no longer serves both tribes' interests and a leader showing initiative would drop the alliance or attempt to strengthen its ties (which was not possible/logical in this case).
Also when the new tribe was made with new leadership, members and the works, the new tribe should not be expected to carry over previous ties/alliances/agreements as made by the leadership of previous tribes. Instead the tribe should attempt to redefine its relationships (which was possibly one of the reasons for the new tribe). Twist could not carry over ANARKY and Skill's relationships (for example) as some relationships contradicted others.
Only fault I can see is if they attacked TSL while in Skill. I would've thought they'd attempt to establish predefence completely before this (or maybe they already did). But the past is the past, and whether we went into this war as friends or despising each other for unethical actions, the war was inevitable.
On topic, the real question is whether Twist can stabilise after the losses of certain key players (such as firey, smintie, martinI etc) or will the tribe continue to lose members till it ends up being TSL vs about 20 tiny tribes in the final war
ha ha... or maybe TSL vs reformed Skill and reformed ANARKY, which would be quite an awkward war no doubt! lol
