You must be joking, america wouldn't attack iran in a million years. This may look stupid in this dominant western forum, but iran has come on top of this, they ended up the smarter partner.
If America attacks iran, iran will secretly develop nukes, noone will know!
If America doesn't attack iran, iran will develop the know-how on to make nukes (enrichment technology) and make it if threatened.
If America attacks Iran, iran has enough agents and troops and special forces in both iraq and afghanistan to make 500 explosions in iraq every day with far more advanced bombs than the most advanced ied's in iraq today. There is so many scientists in those nuclear plants who are russians, north korean, chinese, probably some pakistanis too. Then there is the risk of the nuclear dust after the explosion, if israel does the strike, iran will most likely launch hundreds of shahabs at israel's nuclear plant which will be far more devastating for israel as they have no oil and they need the nuclear plan to electricity.
Iran's influence in the region is by far iran's biggest weapon. Iran has also armed and trained the badr army of iraq, it will be a battle 100x worse than falluja in iraq if iran is attacked, Iran is a pretty rich country in real terms, but the mullahs generally contribute alot of the oil revenue with other SHIA'S of the world, mostly IRAQIS and Lebanese, so these shia's would fight hard on Iran side because of the support iran has given them since the 1980's.
Then there is the element of the kurds who are split, iran supported the kurds since the 1980's both in iraq and turkey, they are split, some on iran's side and some against iran.
An attack on iran would only mean many more body bags wrapped up in American flags / british flags sent home. Iran would simply start the enrichment in secret, you can destroy the technology, but you can't destroy the know-how iran has, they most likely have secret labs already and have already though about such an attack.
Before anyone even thought iran would ever go nuclear, iran has planned this all out, it's well thought out and it's why iran is so defiant, because america or israel can't do much to iran, the best they can do is completely destroy 1-2 nuclear sites, not much of an achievement when you think about the consequences for both sides.
I like something about Britain, that’s they are very smart, unlike America, after the iran iraq war they re-opened their embassy in iran because they knew iran would be a valuable asset in the area, America is like a big beast, they are generally not very smart, but show their muscles around to scare off the competitors, Britain is the small guy who uses his brain instead of it’s muscles, does attack, but does it under a shield.
America’s biggest mistake was the support of iraq in the iran iraq war, then the total breaking of diplomatic relations with iran. Many don’t know the history but it was actually Britain who removed an Iranian king to replace him with reza pahalvi (his son) who was extremely pro western. But look how Britain came out of this, and how America came out of this. The whole coop of mossadegh was the idea of MI6 in Britain, because mossadegh (then iran’s only democratically elected prime minister) wanted to nationalise the oil from british oil firms, I don’t know how but Britain must have somehow convinced cia to take part in the coop too, Britain has far more to gamble on iran’s oil than America, perhaps America though iran may end up in the hands of the soviets along with their oil. But anyways, the whole point is people of iran shout death to America, Israel or the soviet union, you hardly hear death to Britain while it was Britain who had masterminded this whole crazy politics of iran.
