If frodo was in the tower of Minas Morgul

frodo was in the tower of cirith ungol.

but I don't beleive thatss the point of the thread, but what do I know??? I am going to put it simply, if frodo was in minas morgul he and the world was over.

Tar-Ancalime there's always a chance for something better.There's a phrase in my own language which I'll try to write in english:
"From every situation without an exit,there're 13 more exits which you may use"
That's why I think Frodo would have a chance 1:1 000 000 000 000 but still a chance.
