Isa (AS) will not force anyone to believe - you have so misunderstood what our remarks have been … Rather he will merely look at them or breathe on them and enlightenment will overflow in them resulting in belief - except for those people who spiritually dead and blind to the light … they are the ones who will fight and simply die without being physically struck …
If anything the first part of the ayat will be getting fulfilled not the second part … Since Isa (AS) is an agent from Allah (SWT) it will be the Will of Allah (SWT) for this to happen and no one will force anyone to do anything - it will happen rather miraculously.
