Would Beresford have demanded Hood's modernization?

Had he lived until 1941, would Beresford have attacked the Admiralty for failing to modernize Hood?

Yes, in this counterfactual assessment. His earlier opposition to building her would not have prevented that criticism.

The counterfactual assumes Beresford lived into 1941. The prediction is that he would have attacked the Admiralty for failing to modernize Hood, despite having opposed her construction.
