what if Hitler had been captured alive?

All academic now of course ,however what if Mr A. Hilter esq. had been captured alive how would he have been dealt with? notwithstanding keeping the Ruskis away of course,

!. Simply execute him.

2. Hold an elaborate trial .

3. study him in depth using the gleaned knowledge as a yardstick /stereotype

4. have the leading broadcasters of the day interview him ie, Ed Murrow. Richard Dimbelby.

Idoubt he would have been executed as the victorious forces powers would all have wanted their “own time ” with him.its an interesting thought .
