It became abundantly clear that by November even when Burya Pustyne's intended end date of January 31st, 1981, the goals (which were to crush the Iranian government or severely weaken it that it will collapse in mid-February), would not be accomplished. A pro-Iranian president-elect in the United States made it even more obvious. Despite the best of their ability, videos of Khomeini's sermons made its way to Red Iran (as it was beginning to be called in Western media) and Iraq, which caused problems for the annual Arba'een pilgrimage in Karbala, Iraq.
Every year around late November, Shias embark on a pilgrimage to Karbala. Late November is around the time the forty-day mourning period after Ashura ends. Usually >10 million Shias go to Karbala, and entire Shia villages and towns in Iraq are emptied out around two weeks before the pilgrimage is supposed to start. A controversy erupted among the Shia, and to a lesser extent Sunni, world when Saddam Hussein, a Sunni, banned pilgrimage for "security reasons", though some suspected anti-Shia bigotry on his part. In response, Khomeini gave a sermon in Arabic (while Khomeini did not speak Arabic, a speech was given to him by his companions who did) calling for Iraqi Shias to go ahead with the pilgrimage and refuse to abide by the ban. A couple days later, on December 3rd of 1980, the sermon made its way to Iraq. Only 200 Shias heeded the call, though that number was enough to cause trouble. Iraqi police tried to make them disperse, but those Shias fought back. After around ten minutes, a riot broke out which continued unabated for three days. As the dust settled, only two of those Shias who heeded Khomeini's call survive; one made his way to Iran and fought for Khomeini and was killed in 1986, the other managed to flee to Turkey and was interviewed in the 2004 Iraqi documentary titled The Karbala Riots.
The documentary's name is what the riots were remembered as. Iraq was suspended from the Organization of Islamic Cooperation and pledged to only return Iraq's membership when the Ba'ath government falls. Iraq defended itself by making fabricated claims that some of those Shias were Iranian and Pakistani agents, but had little to back it up. Noted Shia cleric Ayatollah Mohammad Baqir al-Hakim announced the formation of the Fighters for the Islamic Revolution in Iraq (FIRI), which had the goal of forming an Iran-style regime in Iraq. FIRI was supported covertly by the United States following 1981 through Saudi Arabia (and later, Syria). FIRI was also funded by Pakistan, and had ties with Kurdish separatists in Iraq, which was one of the reasons for the 1989-1990 Iraqi genocide, with Kurds and Shias both being targeted. The Karbala Riots were seen as a pivotal moment in Iraqi history, and today in Iraq December 5th-December 8th are national holidays meant to mourn the Shias that were killed.
Outside of Iraq, the riots also affected the Soviet war effort. Iranian forces had managed to push Soviet forces back to the outskirts of Isfahan, an offensive to reach Birjand was halted, but what could be the most important ripple effect of the Karbala riots was the Qom Uprising. If the map of areas Red Iran controlled was any indication, it was that they had pushed so far into Iranian territory, that they must have been widespread support for them in the places they've controlled, right? The answer, as some began to find out was no. While in some places you can argue there was widespread support for the Rajavi-Kianouri duumvirate, those places were small and were far from each other. Most of the time there was a hushed disapproval - many Iranians saw the ruthlessness of the Soviet forces and were worried that any loud discontent could not just lead to them being arrested, but could also lead to the harassment of their family and friends from Soviet and Red Iranian forces. In Qom, a holy city, the news of the Karbala riots had the people of the city forget their worry. The Soviets had damaged the Fatimah Masumeh Shrine, now their ally opened fire on Shia pilgrims. Clearly, this was more than just a country which declared war to protect their own interests, no - this was a power actively hostile to Shi'ism, a new Umayyad Caliphate. On December 14th, Qommites attacked Soviet and Red Iranian troops, set fire to government buildings and killed "collaborators", who were mostly just those who probably were critical of the USSR, but not enough. A small Iranian exclave was set up in Qom and lasted for a couple days until the USSR sent troops which defeated the disorganized, ill-equipped Qom army. Still, the resistance of Qom to the Soviets was seen in the entire world, and was used by Iranians as a propaganda tool, and to this day it is remembered on every December 14th as Qom Martyr's Day in Iran. The 1983 American film Loyal To The End shows a portrayal of a Unionist exclave in Mississippi during the American Civil War, though its inspiration is clear - at the end of the opening credits has a dedication: "This film is dedicated to the courageous people of Iran".
As if the Soviets needed more of it, the crushing of the Qom exclave just led to more bad luck. More and more Iranians were becoming soldiers, more and more Pakistani and Arab weapons were being sent to Iran, more and more Muslims were going to Iran to fight for Khomeini, and with the Qom Uprising being crushed, now the Soviets were being driven out of the outskirts of Isfahan, and Khomeini and ordered the (almost destroyed) Iranian air force to attack Soviet targets on December 29th, but the Soviet response made the almost destroyed air force completely destroyed, yet one of the small raids led to the death of the perpetual Soviet Foreign Minister Andrei Gromyko, who was visiting troops in Tehran. The death of such an important figure in the Cold War had surprised many, and further cemented Carter's beliefs that funding Khomeini was a bad idea. Reagan sent his condolences, though privately he was not so convinced.
As 1980 turned into 1981, the next meeting of the Soviet government had everyone distrusting each other. Burya Pustyne was an utter failure, no way the Soviets were going to occupy a country as large and anti-Soviet as Iran in such a short time. At least Afghanistan went through a communist revolution, which could explain why Afghanistan was fairly easier, but Iran had gone through an Islamic revolution, and trying to fight that would be extremely hard. Some Western commentators had joked about the irony of the USSR trying to suppress a revolution they feel would cause problems in their own country, as many Europeans and Americans wanted to do the same to the Soviets in the 1920s, and such jokes really got to some Soviet politicians. As morale on the Soviet government was decreasing, nobody could decide what to do after Burya Pustyne. Withdrawal was not an option - if the Iranians weren't going to do anything after Aliabad, after the invasion they definitely will. A few still stuck with Burya Pustyne, arguing that while it might not reach the intended end date of January 31st, there was a chance Iran might break by the end of February.
Ultimately, the prevailing plan was an Afghanistan spillover, where Soviet troops in Afghanistan will attack Iranian Balochistan and set up an independent Balochistan there, and aid Soviet troops in Eastern Iran. At the same time, Soviet troops in the far northeast of Iran will go to Afghanistan to be in place of the Soviet troops which left Afghanistan. It was agreed upon on January 6th, and it took exactly one fortnight for Soviet troops to be prepared. As Soviet troops began to attack Balochistan, Ronald Reagan took the oath of office. It wouldn't be long until Iranian fighters received M-16s.
