So, who is at war and is attacking iran?
There have been numerous countries, that have committed acts of war towards Iran. Including blowing up military sites, assassinating scientists, funding terror groups within Iran, economic sanctions, continuously threatening an all out war, cyber attacks etc do you want me to go on? And this is only current stuff, you dont have to venture too far back to complete acts of war.
It's everyone's business when dealing with a religious and political regime that openly murders and imprisons people who happen to disagree with its state issued line and calls for the death of foreign nationals for the slightest perceived insult.
What like the fanatical regimes that have been involved in illegal wars around the world, like the fanatical religious regime that has imprisoned an entire population of people because God told them to, that imprisons political figures who disagree with their apartheid policies? How Iran govern their country, is upto them.
The Shah might have been a dictator, but in terms of regional stability he was better than any of these crazy ayatollahs we have had since. A point worth stating yet again; something our western liberal democracy ignores time and time and time again - muslim countries don't want western democracy - and we cannot get our heads round the fact that unfortunately some of these countries with brutal dictators need to have brutal dictators in charge to keep the really crazy fanatics with a jackboot firmly on their necks to keep them under control... the dissolution of iraq is just such an example.
It's not fair, and it's not 'our' system, but that much is abundantly clear already.
Ooh now you support brutal dictators, yet you oppose leaders that have not started any wars in the last 100 years? Arent the ayatollahs effectively brutal dictators too? So perhaps you support them too. Its not up to western nations who runs what country.
Sounds to me like you've really got a hard on for iran.

I appreciate the double standard to which you are trying to allude, but seriously, you think iran is a good and benevolent place to live and the sort of country the rest of the world should allow to have a bigger stick with which to project its less than secular view of life on the region of the middle east and by extension, the rest of the world?
Sounds like you have a hard on for western imperialism, Iran has every right to defend itself and ultimately that's what its aims are. Its doesn't take a rockets scientist to understand what is going on around you in that region. Its none of the rest of the worlds business, when they do the same as what they accuse Iran of doing

Do as I say not as I do, springs to mind, and quite frankly under no circumstance is that correct.
If you think that without any western 'meddling', iran would become some paragon of middle eastern peacemaker, with no designs on regional control or influence, content to do its own thing, then you need to take a good look at the way the middle east works, and understand why it is that western countries meddle in it with overtly very little to gain in the short term.
Why does Iran need to be a paragon of the middle east, is Israel as such? (yet we support them) are the US as such? And yes if it wasn't for western meddling Iran might not be so hostile towards us, can you not see that? If Poland funded, trained and supported the IRA to become the rulers of the UK in a bloody takeover, do you think the UK would be friendly with Poland once they had freed themselves? If Poland armed the French with weapons and chemical weapons and supported them in a war against the UK, do you think we would be friendly towards them? Do you not think the UK would do anything within its power to make sure that that never happens again? Whether that by political means or by military means?
