Jonathan Pollard, a U.S. citizen, and Ben-ami Kadish, a U.S. citizen who has since renounced his U.S. citizenship and is
now an Israeli citizen and whose case was linked to that of Pollard's, are both in U.S. federal prison for spying on our country's secrets for Israel. Before these two, i had never before heard of anyone spying on our country's secrets for another country which is an ally of ours. Are there any other cases during our country's history in which our country's secrets were spied on for one of our allies? Of an ally of ours spied on for our country? Of any other country spied on for its ally?
