Seventy French destroyers improve Churchill's bargaining position

Would Churchill still seek American destroyers and other aid?

Possibly, but roughly seventy French destroyers remaining Allied would let Britain negotiate from a less desperate position.

Churchill might still seek American destroyers because the timing of his historical approach leaves that possibility open. Roughly seventy French destroyers remaining on the Allied side would provide a substantial additional force. Their availability could make Britain less generous in the terms it offered for the American ships. Whether the agreement still occurs remains conditional.
