My thoughts on the Iranian President aside, I actually agree with the idea. Language policy, planning and implementation ensures consistency within the language itself.
A clear example of the price English has had to pay for the lack of an English Academy or similar authoritative regulatory body is the myriad foreign plurals in the language such as octopedes (for octopus), bacteria (for bacterium), and ulamah (for mullah), etc. Then we have phonetic exceptions (zz in pizza and Nazi, pronounced 'ts'), and spelling exceptions (Greek words with the letter phi, such as philosophy, physics, phylum, phonetic, sphere, etc.). One way of ensuring the internal consistency of a language is in fact through the establishment of a language academy and the promotion of its recomendations for a priori as opposed to post priori neologisms.
