Iran is not aggressive but being independent and free (in term of foreign policy making) is usually perceived by few who fear the rise of a competitor as being “aggressive”.
(Mohammad Javad Zarif, Minister of Foreign Affairs of Iran, responded to US warnings to sink Iranian speedboats)
Every action that various countries have taken in western Asia obviously has produced some reactions by the states located in that region.
>> The absurd approach of forcing the creation of the state of Israel literally changed the fate entire of the region and world. The 1979 Islamic revolution in Iran was massively influenced by the conflict between Palestine and Israel. IN my opinion, if it wasn’t for the issue of Palestine, Khomeini wouldn’t have had enough determination and enthusiasm to become the leader of the revolution.
>> All the blood and controversies of the 1979 revolution in Iran rooted in the US, the British and the Soviets rootless policies since the WWI with respect to Iran.
But these days Iran is accused of being aggressive only because it has resisted foreign countries attacks. it is quite remarkable to my eyes when the US and its allies call Iran aggressive for developing missile technology as the only means of its defence while at the same time selling hundreds of billions worth of state of the art missile to Iran neighbours! This doesn’t make sense anywhere in the globe. India made nukes because China got nukes, and Pakistan got nukes because India got nukes. This is how it works. Everywhere. For example, NATO violated the treaty and installed many Air Defence System batteries surrounding Russia (taking away their strike capability) and Russia in return made Supersonic cruise missile that can bypass those air defences easily. Therefore, if the US help Israel by money and resources to build whatever kind of weapons (F35, iron dome, Tanks Nuclear Bombs Uranium etc) that they need or sells hundreds of billion dollars military equipment to Saudi Arabia and other Persian Gulf states countries, then we all should expect the most influential country (arguably) in that region to get worried and feels the need to acquire some form of deterrence to avoid being inavded like in 1980 by US/Soviet/EU backed Saddam.
(Javad Zarif gave the most precise and concise answer with regards to the missile)
Afghanistan and Iraq
When the US decided to occupy two of Iran neighbouring countries, Iran offers help to avoid what everyone had in mind (US war with Iran). The US accepted Iran help in toppling Taliban in Afghanistan and that is why the primary operation went very smooth but when it came to Iraq, Bush rejected Iran offer and instead called Iran axis of evil. In other words, Iran thought they might be next soon or later if the US forces remain in Iraq in mass. Many in the US main think-tank like Hudson institute hate Iran for helping Iraqi militias push the US occupying forces out of their country, which means the some in the US are angry on why you fought back when we popped all over your country and dropped some more uranium depleted bombs on your children as a memorial! This is really unbelievable the level of arrogance!
They themselves replaced the Suni Saddam who was a CIA stooge, with a new system that happened to be run by the Shia prime minister after the elections! Then under the US supervision, ISIS is created and kept growing but they somehow dare to accuse Iran once again for that!
Why Iran somehow was in Iraq?!
As ISIS, advanced 30 km to Iranians border and the US simply rejected an emergency call for help from the Iraqi government on ISIS offensives to Baghdad and Erbil, Iran received two calls one from Kurdish authorities and one from Baghdad, demanding immediate support and Iran without saying anything further deployed heavy military equipment plus several hundred special forces in one night which repelled the ISIS offensives. Is it Iran being aggressive here?!
The only reason why Iran has some presence in Syria is due to the fact that the US and its allies created a Jihadist production factory in that country.
>> US/ allies made a systematic effort to find every psychopath, criminal and terrorists from all over the globe (Chechnya, southern Russia, eastern Asia, Saudi Arabia etc) and deployed them to Syria from the northern border with Turkey where Erdogan-ISIS dirty oil trade was going on and from southern Syria, through Jordan and also from the Israel occupying Golan Heights. Iran with so much suffering managed to keep them in line until Russia provided airpower to stop that cancer before it was too late! They did everyone a favour, especially the European!
Iran is not aggressive, in fact, Iran has been entirely pretty defensive but effective and firm on its moves (because it’s defensive simply wanting to survive) whereas other parties just made reckless policies as if its a game, because it is a game for them when you’re defending your existence, your entire being, you’re more likely to be effective and determined, whereas imperial kind of policies are superfluous and lack determination.
