Back in WWII, the Iranian government rescued over 1,500 Jews and secretly granted them Iranian citizenship, allowing them to move to Iran, in order to save them from the Nazis. Here is how today's Apartheid state of Israel shows its gratitude: by continuously pushing the US for a war against Iran.
For many decades, Iran and the German Empire had cultivated ties, partly as a counter to the imperial ambitions of Britain and Russia, and later, the Soviet Union. Trading with Germany appealed to Iran because the Germans did not have a history of imperialism in the region, unlike the British and Russians.
The Iranian government did not support the antisemitism of Nazis. Iranian embassies in European capitals occupied by the Germans, rescued over 1,500 Jews and secretly granted them Iranian citizenship, allowing them to move to Iran.
