The death of IRGC commander Major General Qassem Soleimani was the culmination of years of provocative attacks on United States and allies within the middle east. It’s no secret that the Iranian Revolutionary Guard Corps and “Qods Force” have been actively helping the Assad regime against ISIS/Daesch, and actively provoking Iraqi Shia Militia Groups to attack coalition bases (the Government of Iraq requested assistance from the international community in 2014 to fight Daesch, and the terms of that assistance is that when they ask the international community to leave there is a year to complete the exit). So far the Government of Iraq has not officially asked the coalition to leave, so rocket, mortar and small arms attacks on coalition bases are simply proof that the Government of Iraq cannot control the Shia Militia Groups aligned with Iran.
I won’t go into events prior to January 3rd, 2020, suffice to say that there is a lot of history and backstory.

So six, give or take, IRGC members have perished from bombs or bullets in the past three months. The only acknowledged “targeted killing” was the 3 January 2020 strike on Qassem Soleimani, the other five were “meh, too bad he happened to be at the location of a known terrorist location” or “hell, stuff just happens in war” or in the case of Mojaddami “two guys on a motorcycle sure sounds like an internal security problem.”
What is pretty evident to me (but still pure speculation on my part) is that at least one government, probably many more, are tired of Iranian Qods Force leadership complicating the political situation in the Middle East and trying to cut back their influence in the Levant. With Iranian influence minimized it isn’t too far of a stretch to see the US, Russia, Turkey, and Iraq coming to a ceasefire agreement with Syria. The Syrian Democratic Forces would get slaughtered by Syria and Russia should the coalition pull out rapidly (not really my problem, but it wouldn’t be a politically acceptable move), which would likely set up conditions for yet another transnational terror group to rise up. My guess is that we’ll see one or two IRGC leaders taken out per month for the foreseeable future.
