Virtually none. It would need to be well over 100k feet to produce any. It would be useful to get an airburst going at 3k-5k feet or whatever though. And of course as a ramming jet. Or bio/chem but that would take a lot of modification that I doubt any smaller group would be able to do.
I think it’ll have either an Iranian or NorK nuke on board and fly over either DC or Wall Street. A financial or political decapitation of the US would set Israel to be invaded by Iran and the Muslim Brotherhood nations surrounding her.
