How do we reconcile the Prophet’s (peace and blessings be upon him) secret entry into Makkah with the statement that Muslims do not break a treaty unless they inform the disbelievers?

Question:
Honorable Shaykh, may Allah grant you success. He says: It is known, may Allah preserve you, that if there is a treaty between Muslims and disbelievers, Muslims do not break the treaty unless they inform the disbelievers. So how is the action of the Prophet (peace and blessings be upon him) to be understood when he concealed himself with his army and entered Makkah upon Quraysh?

Answer:
Because they broke their treaty. If the Messenger intends to end what is... if he intends to end the treaty, he informs them, saying to you: the period is so much and so much, ending this, ending the treaty. But if they are the ones who betray, then no, he does not inform them of that. Yes.
