Cornwell was bullied into saying it is "impossible to judge Pacelli's 'motives.'" Cornwell did not say that Pacelli's motives were good or pure or correct, merely difficult to decipher.
Further, Cornwell does not back off of his detailed depictions of Pacelli's "actions" and lack of "actions," which are fully documented in his book.
Pacelli's "actions" can be judged. And the judgment condemns him.
Prove it.
Wouldn't that make him a coward who lacks the fortitude to stand up for his convictions, ironically exactly what he accused Pius XII of being?
"For the measure with which you measure, so will it be measured back to you ..."
You just LOVE that liar Cornwell.
