Russians will never ever provide Iran with any of these airplanes. Anything, any system that will allow Iran to become economically strong is in opposite interest of Moscow. If Iran goes Nuclear, Russia will have to seat around the negotiation tables with Iran for anything that has to do with Middle East and Iran/Russia affaris. Right now Russians do as they wish without even informing Iran on anything.
A strong Iranian aviation means $$$
A strong Iranian oil industry means $$$
Iran's economical system which is based on U.S. is very dynamic and vibrant it can kick Iran ahead of other nations such as Russia and East Europe in less then 10 years!
This is not a news...the only way for Iran to be free is to become a very strong military power.
Remember what Napoleon Bonaparte said: "The truth is told by the one who has a bigger size cannon."
Iran has to mass produce missiles, guns, bombs, airplanes, tanks,etc
Iran has to build at least 50 nuclear power plants, each power plant has to have 4 plants
Iran has to sell electricity to the entire Middle East, Asia, East Europe, and Africa!
Iran has to be able to light up all homes, and warm up all homes using electricity!
Iran needs to increase the capacity of its current 100 public universities to 2 million!
The first and for most important part of Iran making progress is to first pump money into universities.
This is how Deucthland made huge leaps, they pumpt money into their universities, roads, and health!
If each Iranian university will be able to accomodate 20thousand students and provide them PhD level education in 40 different majors, in 12 years from now Iran will be a different nation.
But waiting for bunch of low life, blood thirsty Russian criminals providing us with their junk will be nothing but a setback.
Look at Russian aviation, they themselves do not use their own airplanes!!
All of Russia's passenger aviation is Airbus and Boeging!!!!!!!!!
