The basic principle in fighting in the Qur'an is that other communities should be treated as one's own. Fighting is justified for legitimate self-defense, to aid other Muslims and after a violation in the terms of a treaty, but should be stopped if these circumstances cease to exist. The principle of forgiveness is reiterated in between the assertions of the right to self-defense.
Does the Koran say anything about destabilising someone else's country and then invading/bombing them on the pretext of protecting the human rights of the people whose countries you have destabilised, because you want to steal their oil?
Permission to take up arms is hereby given to those who are attacked because they have been oppressed – Allah indeed has power to grant them victory – those who have been unjustly driven from their homes, only because they said: “Our Lord is Allah”.
—Qur'an, [Quran 22:39
Nope, nothing here about invading other people's countries to effect regime change or saving them from their oppressive rulers when all you want to do is steal their oil.
