(note: this takes place in the same universe as my previous question)
Hello, fellow comrades.
As you know, we have been gaining in strength lately, exploiting instability in Russia (quick author's note: Russia's unstable because they didn't diversify their economy quickly enough, so their economy basically collapsed as oil, coal and natural gas stopped being used) and the elites' unwillingness to provide for the common people to gain large amounts of resources. This October, we will strike back at the elites, to show them that if they ignore the people, their lives will be under threat.
Our target is the COP52 climate conference in Malé, Maldives, this October. Our plan is to release drones nearby carrying bombs (basically, just like the drones in this video) that will fly towards the conference and blow a hole in the side of the convention area, then the rest of our drones will fly through the hole and blow the people inside up, in a sense. These are some of the most important people on the planet, so we expect that there would be large amounts of security to smuggle the drones from within: this is why we are releasing them from outside.
Getting the drones and the materials shouldn't be difficult. We have large amounts of resources from our donors and our control over parts of Russia, and many experts disillusioned with the global elites support our cause. But the issue is how we will get these drones and materials to the Maldives. Our only methods to get it there, as the Maldives are an island nation, are via aircraft or shipping, and there is no way we can buy our own airplane or a ship large enough to reach the Maldives. Anyways, our ship would be inspected by national authorities, and it goes without saying that our drones are highly illegal, so there's that.
While it would not be optimal, we could deliver the drones and resources to the Maldives and assemble them into terrorist drones on site, though being away from our base in Russia would make it more difficult to assemble the drones with minimal supervision. Acquiring drones and explosives in the Maldives, again, could be possible, but the increased state interference from doing so in a country with a stable government would reduce the number of drones that we would be able to assemble.
We have a large amount of resources from donations and our control over resources in Siberia as mentioned before, so we are willing to tolerate a plan with costs in the millions to tens of millions of dollars, but less expensive methods would be better. Plans that make it harder for any authorities to discover our headquarters are better, for obvious reasons.
We will most likely plan other terrorist attacks against the ecofascist elites in different parts of the world (eg the power cables connecting North African solar panels to Europe, national governments, etc.), so plans that can recycle some of our resources used in this attack would be more preferable as well.
Author's note 2: Remember to keep in mind that this story is set 26 years in the future when thinking about your answer, so technology will not be exactly the same as it is today (eg 3d printing will be more effective, but machines designed to find suspicious materials will also be more effective). Also, there have been past terror attacks using drones (but none on this level!), so the governments of the world will have some countermeasures to prevent drone attacks: in my story, the Maldivian military will cut this attack short by deploying drones of their own, for example.
