Full USA war with Iran would be devastating for both the parties. USA cannot send ground forces to Iran as Iranians would eat them alive, and USA has no interest in occupation of Iran. They only want to send Iran back 50years and this way Iran power in Iraq, Syria, Lebanon, Yemen will collapse. Their world proxies/allies will weaken and will be destroyed and overtaken by the vampires like the Saudis and it's proxies.
The Iranian airforce is no match for the USA and allies airforce so i doubt Iran will use its full airforce nor will it be any effective. Most of it will be destroyed on the ground and those which will fly like the mig29 will be destroyed in the sky.
The USA aim will be to destroy all known nuclear facilities, missile facilities/factories. Destroy airbases. Destroy major military installments, Airports, seaports, economical, trade places, routes. This will set Iran back 50years, their military power will collapse, economy will be destroyed, poverty will increase.
This might take the usa a few weeks of heavy air attacks and missile attacks from the sea.
All this will lead to an unstable Iran and ISIS Alqaida will be able to enter Iran to cause chaos. Remember if Iran military is weakened 50%, economy weakened 50% proxies weakened 50% then the only outcome is unstable Iran full of internal issues and attacks.
Iranian opposition will try to get the power in order to change the regime and become USA stooges. This will continue for decades as Iranian mullas will fight back. This way iran wont be any threat to the Saudi establishment nor Israel so game over.
I fully oppose the war and I think Pakistan should do the same. Iran is our neighbour and a Muslim power. It will make us weaker to have Iraq next to us. We will become more weaker and unstable.
Lastly Iran has 2 options.
1st Either change their stance and accept European Usa proposals and bring peace in to their country but we all know the western world wants Iran to obey them, so they will keep making excuses in order to make you a puppet.
2nd If Russia/China sends their military/airforce to Iran to protect it. This will stop any attack on Iran as this will lead to world war 3. Take the example of Qatar and Syria. if Turkey didnt send army to Qatar then Qatar would have been a Saudi colony and if Russians army didnt enter Syria then Usa/nato would have bombed the country just like they did to Iraq and Libya.
Iranians on pdf think they have the 3rd option of a full scale war with Usa and allies and Iran will come out as a winner is just the reason why the Muslims are in this mess. We dont have the education and mindset in order to become a successful world power like in the past where we ruled the world. Our leaders make powerful speeches and we think we are untouchable. If you look at the Islamic history, our countries were powerful, our children were educated, we invented technology and military was powerful. They didn't just dream of victories, they worked harder than the rest of the world.
In the 21st century we have 50+ countries and we all hate each other. We plot against each other and then we use religion to hide our weaknesses. Iran needs to play it's cards right otherwise it will be it's downfall. Will India come to Irans rescue?
I hope Iran has security pack with Russia or China just incase of an attack. Iran needs to leave India and join China camp.
