From whom?

When they're behind enemy lines, I'd say they're on offense.

I think they mean insurgency as in resistance in occupied areas.

Yes, indeed. Can you buy or build a drone in the US? No problem. Can you get explosives or other nasty stuff to arm it? No issue for a determined group. Can you find an undefended soft target? Of course, there is a smorgasboard of those.

I think basically everyone except North Korea is. Anyone who allows goods and people to move through their borders with any level of freedom can theoretically get attacked like Russia did.

One person making a drone is far different from China staging an attack.

Then they’re commandos or special forces. ‘Insurgents’ implies an uprising against a central government, and serves to reinforce the Russian narrative of Ukraine being part of their empire.

The attack on Moscow’s strategic bomber fleet was not carried out by resistance fighters in e.g. Crimea, which would be the implication under that interpretation.

Exactly, it's a modern day trojan horse. It seems to be fairly easy to then potentially pin the attack on just about anyone using shell companies for shipment. Especially with the deregulation and removal of so many safety and security positions over the last several months.

I was reading a little about the beeper attacks the and I think even now there is still some uncertainty about which company actually worked with the Mossad to manufacture the batteries that contained the explosive.

The only reason I even bring that up, is that there were so many steps involving so many different groups of legitimate manufacturing companies as well as shell companies to ship the beepers. Some of the beepers were even taken apart and inspected before being distributed as a security measure, but they had used such a small amount of explosive fuel within the batteries, that it was completely missed.

Unless there's another beeper attack I missed, the one last September was directed at Hezbollah, across Lebanon and Syria.

It isn't hard to make a drone. I have confidence that I could do it, and I've never tried. They are available off the shelf, and nobody will bat an eye if that becomes my hobby - just keep a few around and ready to fly with cameras and post photos of my various outings and I look just like any of dozens of other people I know who have drones.

I would need a place to test my first attempts, but it isn't hard to find a farmer's field in winter where nobody will see what I'm doing. Which is to say I couldn't stage such an attack today, but I could next year.

The author seems like a total dick, but given the recent fear/rumor of the possibility of a false flag attacks on U.S. soil, I feel like something like this isn't inconceivable.

The Billion Dollar Question.

Japan tried to bomb the US by sending balloons over the jet stream and it was largely ineffective due to the range and lack of precision. Moving a weapon across an ocean and into range of a target without a ton of telecommunication support and manual intervention would be a herculean task. Far easier to just bomb one of the hundreds of US military bases local to your neighborhood, as with the Al Qaeda bombing of the US base in Somalia or the Houthis in Yemen targeting US bases and large ships trying to navigate the Red Sea.

But domestically? A little surprised nobody has tried to turn a large drone aircraft into a weapon for an Oklahoma City style attack.

If you look at the techniques employed by the Ukrainian insurgents against Russia, explosives embedded into the shipping containers of large trucks have been incredibly potent. Drones hidden within the tops of shipping containers put Ukraine within striking distance of the Russian bomber fleet.

Definitely something a committed insurgency within the States could employ against police/military.

...into a weapon for an Oklahoma City style attack.

In terms of the actual explosive, I think that was a whole lot of mass.
