Repeated to Tokyo No. 22.
My telegram No. 373. 
Information contained in my telegram No. 378  was conveyed to the Secretary of State  in a form that irritated him considerably and caused him to tell the British Ambassador  quite abruptly that he did not appreciate being lectured by the British Government on how to conduct himself. The incident will take at least a few days to blow over.
(2) The British Ambassador meanwhile has received instructions from London to the effect that, following on the speech of the Netherlands Minister for Foreign Affairs  on May 5th and subject to the concurrence of the Dominion Governments concerned he should inform the United States Government confidentially that the British Secretary of State for Foreign Affairs  proposed to make a public statement closely corresponding to that of the Netherlands Minister for Foreign Affairs and saying, in effect, that we will join with the Dutch in defending the line from Malaya through the Netherlands East Indies to New Zealand.
I have discussed the above proposal with the British Ambassador and I agreed with him that in view of the first paragraph above it would be inexpedient to say this to the Secretary of State at this moment as it would be likely to be interpreted as arising out of the above incident and to indicate the decision to go our own way in the Pacific independent of the United States which might have unfortunate results.
The British Ambassador has telegraphed the British Secretary of State for Foreign Affairs suggesting that he (Halifax) should call the Secretary of State's attention to the speech of the Netherlands Minister for Foreign Affairs and to the fact that the Dutch have been pressing His Majesty's Government for a statement of the intention to defend the Netherlands East Indies and that the British Government believe that they must in the near future give the Dutch assurances they seek. Halifax suggests then asking for the views of the United States Government as to whether such assurances should be public or confidential.
There is also this point. It is well known to Japanese that United States, Dutch and ourselves have been in active discussion on the Far East problems. If we now announced defensive agreement with Dutch, Japan may well make capital out of non-participation of strongest party.
I believe, therefore, that a confidential undertaking with the Dutch is preferable at the present stage to a public statement.
Approach suggested in your telegram No. 47 from the Acting Prime Minister  has been delayed for the reason given in the last sentence, Para (8) my telegram No. 373.  I believe that the State Department may be ready to talk by June 2nd. I will, of course, co-ordinate the views with British Embassy and make joint approach with them.
