A Phoney War campaign against German waterways and industry

Should Britain and France have used the Phoney War to mine German waterways and disrupt industry?

The proposal is interesting, and the RAF did carry out some mining operations, but the full counterfactual is not endorsed.

The viewer argues that early Allied air power could have mined German inland waterways and harbors while the opportunity still existed. Such attacks might have obstructed Swedish iron ore moving to German factories, limited civilian casualties, and reduced the risk of turning American opinion against the Allies. The comment also contrasts relatively secure British industry with the uncertain support Germany could expect from recently occupied Czechoslovak industry. The Royal Air Force did conduct some water-mining operations, which makes the broader proposal interesting without establishing that it was guaranteed to succeed.
