To "win?" No - not really.
But I don't think that matters much.
Honestly, I think that Trump and the overt fascists and plutocrats who are backing him fully intend to get him into office or destroy the country trying - that if he doesn't win legitimately, he'll "win" through fraud, or through the machinations of the brazenly corrupt and compromised supreme court, or through violent revolution.
His backers - the Heritage Foundation and the rest of the fascists and Musk and Thiel and the rest of the plutocrats and so on - don't just want to try to get him into office - they want to destroy American liberty and democracy. It's not even so much about him specifically - he's just the right combination of charismatic and shallow that they see him as their opportunity to impose the autocracy they want. And I don't think they're going to let anything stand in their way. So whether or not he actually wins the election isn't even really relevant, other than to the degree that that will determine what other strategies they might have to, and will, implement.
I think it's safe to presume that Iran hasn't retaliated yet, and likely won't retaliate in any direct military way, because that's exactly what Netanyahu wants them to do - that was the entire point of the assassination in the first place.
Though Iran arguably loses face by not diectly retaliating, they'd likely lose even more face by allowing themselves to be provoked into doing what Netanyahu wants them to do.
Alongside that, it's safe to presume that they will retaliate at some point, but it's going to take a form that conveys a clear message to Israel and to Netanyahu while not being the direct military response that Netanyahu was trying to provoke, so won't give him an excuse for the war he wants to drag the US into.
