You're right. That would be silly. King wasn't making a prophecy nor was he talking about Trump. Coincidences do exist, as do ikenesses.
Political assassination, is not an uncommon thing, especially in works of fiction. They make for great stories.
The video was taken in April and would've had a 6 month periodnin which it could've happened, and he was explicitly talking about Trump in the context of prophecy. 🤷♂️
For me, that's a difference.
