“No, man, that’s my walking stick - I gotta bad back!”
This is all very thinly sourced, but given the state of the world and the US “establishment”, the broad outlines are not only credible, it’s almost unimaginable that bad actors would not take advantage of the opportunities created by the current administration. The case could be made that the head of a hostile power’s intelligence services would in fact be derelict in his duty if he didn’t at least put assets in place.
But the specific charge, that Iran would infiltrate an Iranian team, using Iranian ordnance to conduct a high-profile strike on US soil is just a little too on-the-nose.
Seems much more likely that the DC elite Blob sees an opportunity to accomplish two goals: take out Trump, and start the war with Iran that they’ve been salivating over for years now.
