You have a rather peculiar view of history. I'd suggest you read up on the response of the Irish to famine and starvation in 1846-7. And the Ukrainians during the famine and starvation of 1932-3. And the German people in the latter stages of WW II.
Starving people rapidly lose motivation, become listless and passive. It has been thus in every case, from Africa to the real life examples mentioned above. Iran had its chance to rise up when they were well fed. They failed. History says starving them will accomplish nothing. Your theory is at variance with reality.
The French Revolution
The Fall of the Soviet Union
Bosnia
and many others.
You have a twisted view of the response of Germans in the latter part of WWII.
