what if

[Unregistered]

Dear teachers.

I wonder if there is any difference between (1) and (2).
1. What if we are wrong?
2. What if we were wrong?

[Mister Micawber]

(1) refers to the present possibility of being wrong.
(2) refers to either the present impossibility of being wrong, or the past possibility of being wrong.


Try:

'What if he is wrong?'
'What if he was wrong?'
'What if he were wrong?'
