Does the treaty of a disbeliever state with all Islamic states become void if it invades one of them?

Question:
May Allah reward you. This questioner says: What is the ruling if a disbeliever state invades a Muslim state? Does the treaty of this disbeliever state with all the other Islamic states become void?

Answer:
No, no. except for a people, look at the condition: and you have recently learned that what a Muslim state is upon does not bind another state. So, if the ruler of a region or kingdom makes a contract or treaty with them, it is permissible for another Muslim ruler to attack them, and this is not considered a violation of the custom because he did not make a treaty with them.
