Answer

You want this meaning: "cause to become vulnerable or function less effectively"  . A secret mission was compromised means that someone found out about the mission so that it was not secret anymore.  " compromise principles" means that the person would have to act against his own conservative beliefs in exchange for something.

Answer

For example, if the Libyan government has planned  a secret military mission to invade Egypt, and someone in the Egyptian discovers that the mission is being planned , the mission has been compromised. Then if the Libyan government knows that the Egyptian government knows about the secret mission, of course they will abandon the mission,  because it is no longer secret.
