Its harder. 20% of Russians(my estimate) have connections to Ukraine (relatives, friends, or were born there) and could be Ukrainian agents, there are lots of land routes how you can smuggle stuff. Things are not as well connected between Iran and US.

Agents in the US would just be normal citizens asking for money/crypto. You'd need to find fools to deceive, but a lot of people fall for scams to get small gains. Many hard drug users in particular are often rather self centered in my limited experience.

Or if you wanted to attack refineries, you could possibly select some climate change activists to do it for you?

Or find angry children to do it. Make things go bang for fun.

Our industrial infrastructure appears to be vulnerable to me (as a superficial opinion).

The real fix is to help poor people in other countries to like the US. And work hard at avoiding doing things that radicalise dangerous haters.

I believe all those pools of opportunities are much smaller to what Ukraine has in Russia.

It seems to me that there a large and well-established drug smuggling industry that might be quite interested in Iranian drone technology and has long-established logistics competence regarding transport into the US from distant countries. (I searched for 'fentanyl precursors' now, some search results named very distant sources.)

We're getting into Tom Clancy novel territory here.
