There-in lies the challenge to your imagination:

Perhaps they are having political problems at home, maybe a facist group is taking over their government, maybe they're secretly being assimilated by another unknown race. Perhaps it was a misunderstanding. Maybe their conflicting orders when out, your planet was attacked and the current administration has 2 choices: admit the war was a mistake or continue it to the end to prove it wasn't.

Hmmm that Last one has potential...
