Fine...


 * Galuna: Gray was beaten up badly and the village was destroyed, so they went to take revenge.
 * Fighting Festival: Laxus' "minions" attacked the girls and thus the entire guild rushed of to take their anger out on Laxus, though with the "fighting game" he forced them into fighting each other instead.
 * Nirvana arc: The alliance was beaten up and Wendy kidnapped right at the beginning.
 * GMG: First it was against Raven Tail for their cheating and attacking Wendy and supposedly Lucy and later against Saber Tooth for hurting Lucy. In the end Natsu went nuts over F-Lucy being killed, so here we even got this theme trice.

I know it wasn't their main or only goal to take revenge (but then in Phantom Lord it was so only for a short time, before the goal became survival, rather than revenge), but Natsu shouting that they'd go to war in the heat of the moment isn't any better.

For all we know Makarov will just smash Natsu into the floor right on the first page of the next chapter for being stupid. After all Tempesta didn't specifically go after Fairy Tail. They just happened to be in the way., while in Phantom Lord they were specifically targeted.
