I think Mifsud was never a real intelligence operative. Smart guy, had years of intellectual foreign affairs education....maybe gifted at conversation and ‘chatter’. I think once he was plucked-up to be the head of foreign affairs in Malta, he came up on the screen as a useful tool, and a think-tank crew (maybe two or three) started to groom him, and he was there just to go and convince people of certain agendas or political directions. These oligarch/billionaire types were the ones to gain, and have a profitable position on outcomes.
I don’t think he had any preference over Trump....he was just there to ensure the downfall of those around him, and ensure a tactical advantage on the board for some new position-grabbing group.
He was at the very least an intel asset of the West—and apparently with up to three services: the US, UK and Italy.
I have no idea why you would attempt to underestimate him.
