Which bases? Dear Lord, so many! Let's start with Whiteman Airforce Base in Missouri. They'd probably divert to Diego Garcia after the first evening of festivities, just to shorten their daily commute.
As you may be aware, it takes persistence to close down ONE air base. It takes MUCH MORE to close down many. On day 2, runways would be repaired, casualties evacuated, aircraft replaced. On that same day 2 for Iran, there would be no air defences , no power grid, no communications, no transportation, no anything. By day 3, the Mullahs would be wondering where they can escape to, to spend their stolen billions. Oh too late, those assets have been frozen/seized.
And once the IRGC is destroyed, what will the Iranian people and Iranian military do? Lots of unanswered questions when you open Pandora's Box.
Also, what will Israel and SA do after the first few days when they see Iran has been rendered defenseless? Lots to think about.
The same Saudis and Israelis that are flanked by proxy groups that are loyal to Iran? The same Israel that failed to defeat Hezbollah in 2006, and now has to live with a semi IRGC division next to its border that has more than 100.000 rockets (including guided missiles) in its arsenal? The same Saudi that faces weekly ballistic missile + drone attacks against it critical infrastructure, having failed to defeat the Houthis in 5+ year old conflict?
Iran influences an area that spans all the way from Afghanistan, Red Sea to the shores of the Eastern Mediterranean. In any conflict with a regional or international actor, Iran will unleash a fury of missile attacks that will set fire to the entire region. Dubai and Abu Dhabi will be utterly destroyed; the Saudis will lose all of their oil fields within minutes; Israel would be confronted by a determined Hezbollah that has the ability to hit every point on Israeli soil; every US base in the Middle East will face unrelenting attacks of ballistic and cruise missiles from every angle imaginable.
The idea that the US can keep these bases operational in the face of missiles, drones and rockets is absurd. If the Ain al-Asad attack has proven anything, it is the absolute horror that the soldiers at that base experienced when those missiles were hitting pre-arranged targets. We have reports of American and Danish soldiers being completely paralysed, crying out loud and refusing to leave their bunkers even hours after the last missile struck the base. In addition, it took a little more than a dozen of missiles to leave 100+ Americans with traumatic brain injuries that left them too injured to continue operations. And Iran did not even really try to cause casualties.
Now let's agree for the sake of the discussion with Ivan le Fool, who summed up all the bad things that Iran has done in the Middle East for the past decades, including causing hundreds if not thousands of American KIAs, supporting proxy groups, attacking ships in the Persian Gulf, supporting Hezbollah against Israel, advancing its nuclear program up to the point of nearly being a nuclear threshold state; building an advanced missile arsenal that could hit every corner in the region; etc.
Why hasn't Iran been attacked thus far? Israel has subdued countries for far less. It attacked Syrian and Iraqi nuclear facilities when they were in their infancy, yet it has allowed Iran to build a nuclear industry that is much more advanced and underground than anything the Syrians and Iraqis have ever accomplished. Failing to conventionally confront Iran for decades, it has resorted under the security umbrella of the Americans to assassinations and cyber attacks which the Iranians easily have overcome. The Americans primary weapon, sanctions, have similarly failed to force Iran on its knees.
You guys are trying hard to sum up reasons why Iran should be really afraid of the all-mighty Americans that reportedly have all kinds of wonder-weapons available to them that could quickly neutralize the Iranian threat whenever they want so (funny how these same wonder-weapons are failing in a 2 decades long conflict against the Taliban). Yet, despite all these fancy arguments, the reality is that the Iranians have hardly flinched. Not impressed by all the technological edges of the yanks and the empty threats of the Israelis, Iran has advanced on all of its strategic fronts: nuclear, missile and regional influence through allied groups and governments.
And this is easy to explain: Iran is heir to one of the oldest civilizations on earth, with a military culture that spans more than 3000 years. It is known for its scientific-minded people that have made all kinds of contributions to the world ever since their ascendency. Its leaders have throughout history been known for their strategic ingenuity and competency for warfare, which is exemplary to the Indo-European nature of Iranian culture. Combined with a highly nationalistic citizenry with strong ideological convictions, and it is of no surprise that Iran continues to defy the strongest actors in the world.
The idea that a proud country like Iran, which would hands down be the most competent and prepared actor the US has faced ever since the end of WW2 if conflict breaks out, would surrender in the face of foreign pressure is ludicrous. You guys are all living in la-la land. The period of western dominance is all but over; the quicker y'all wake up to the new reality, the less humiliations y'all suffer.
