Your airmail report of 9th July.

Your suggestion for an appropriately worded high level appeal from
United Kingdom instead of an agreement containing assurances by
Australia is a happy one. It has many psychological advantages.

The precise content of the letter of appeal, particularly the
suggestion for Australian action, would of course be crucial both
from the psychological and technical viewpoints and I assume that
the appeal would NOT be made without my having approved beforehand
the actual terms of the letter. This is vital.
