What I believe happened regarding Saudi Oil refineries being blown up

First of all, Iran brought down (landed an American military drone) I think a predator, several years ago in Iran. What they did was to change what the drone thought was it's actual location to make it believe it was somewhere else than it actually was.

Iran took this military drone from the U.S. and reverse engineered it and now has predator like drones itself (at least the 10 that hit the Saudi Refinery) or more (I'm thinking many more). So, at this point more drones could quietly fly under any radar to blow up more refineries or Saudi Military installations or whatever. As long as the Iranians fly these out of Houthi territory in Yemen they likely can get away with this and not draw direct fire against the Iranian homeland.

So, how would this be done?

They would either fly them on cargo jets to Houthi territory in Yemen or bring them in on ships into Yemeni ports (either one) or some other way I haven't thought of yet.

This attack on the Saudi Arabia Oil refineries is basically Saudi Arabia's 9-11 right now. So, expect some really crazy stuff to happen in the middle East regarding all sorts of stuff at this point over the next 5 or 10 years.

Is this Saudi Arabia's karma for it's 16 Saudi Citizens who created 9-11 in the U.S.? Possibly. Not sure about this because country or regional karma is pretty esoteric usually. It's sort of like Trump being a reincarnation of King George III and Boris Johnson being someone in King George IIIs circle of power back then too. Like I said this is all pretty esoteric so difficult to fully fathom what it all means on a group karma level (at least at this point). 20 years from now we might be able to do much better than now, for example.

Note: One other way the drones arrived in Yemen would be flying them over the ocean out to sea in international territory and flying them only at night to Yemen. So, either they would be flown (under the radar or up real high masquerading as domestic flights at night with similar domestic lighting or something like this.
