Don't forget that the Mossad helped establish and train the Shah's SAVAK (Secret Police).....countries have been doing underhanded/cheating/corrupt/sneaky/etc operations for decades...this is what SPIES do !!!
...Operation Ajax --US/Brits in Mossadegh's overthrow is a prime example
...9-11--Arabs posing as pilots !!!
..Camp Chapman attack--double agents
...Germans at the Venlo incident
..the US paying off Hezbollah/etc put Americans at risk
etc etc --there are thousands of incidents like it
ah yes-----the hated Savak------the organization that rendered some people so ANGRY with THE SHAH that they put their trust in KHOMEINI---------how they came to regret that sentiment!!!!!!! The Iranians really got SCREWED
