"The CIA considers Israel its No. 1 counterintelligence threat in the agency's Near East Division, the group that oversees spying across the Middle East. Counterintelligence is the art of protecting national secrets from spies. This means the CIA believes that US national secrets are safer from other Middle Eastern governments than from Israel."

USIC personnel don't take any foreign espionage activity personal as this is "business" and we do the same to other countries. For decades, Russia and our so-called "ally" Israel have always posed the number one intelligence threats to US national and economic security, joined later by China which was once considered a localized menace in PACOM AOR. But members of the USIC do take betrayal and treason personally, like in the cases of CIA analyst Aldrich Ames, FBI Special Agent Robert Hanssen, or ONI analyst Jonathan Pollard.

Jonathan Pollard sold US national secrets to Israel, causing exceptionally grave and irreparable damage to US national security. He was been described as the "scum of the earth" by a retired US NCIS Senior Special Agent.
