I imagine the main reason we have not seen uprising in the streets by the freedom lovers is that small arms are not commonly held legally by the people in Iran. I doubt that large numbers can be distributed without our people on the ground in a number of secured places. Probably the Massad has been distributing some, and perhaps the Kurds in their area of Iran.
At this point what might be more useful for the Isreali infiltrators/spys to do would be to distribute items like plastic explosives and detonation instructions, and then placing them along the routes used by IRGC and Basij to go out to intimidate the people and set of at the right time. The Iraq anti US fighters made good use of such methods in the past, and it might be useful against the Iranian intimidaters when they go marching or parading to scare the people.
A recent figure mentioned by Trump as people killed recently by the rulers in Iran was 42,000 if I remember correctly. I recently saw the figure of 90,000 mentioned by a source with direct contacts inside Iran, however I left town for 5 days and did not have the opportunity to explore this figure for accuracy. However, I doubt that the authorities have stopped killing helpless prisoners, so do find this figure believable.
Remember Trump's statement on the Kurds betraying him, and keeping the weapons he sent for the protestors.
"President Trump told me the United States sent guns to the Iranian protesters," Yingst related to the Fox & Friends Weekend hosts. "He tells me: 'We sent them a lot of guns. We sent them through the Kurds,' and the president says he thinks the Kurds kept them." "He went on to say, 'We sent guns to the protesters, a lot of them,'" Yingst added.
