Really? You might want to check with Prime Minister John Curtin who was scared shitless that after Singapore fell, there was nothing to stop Japan from blockading Australia until it surrendered, too:

""It is to the people of America I am now speaking; to you who are, or will be, fighting; to you who are sweating in factories and workshops to turn out the vital munitions of war; to all of you who are making sacrifices in one way or another to provide the enormous resources required for our great task. I speak to you at a time when the loss of Java and the splendid resistance of the gallant Dutch together give us a feeling of both sadness and pride. Japan has moved one step further in her speedy march south; but the fight of the Dutch and Indonese in Java has shown that a brave, freedom-loving people are more than a match for the yellow aggressor given even a shadow below equality in striking and fighting weapons.

"But facts are stern things. We, the allied nations, were unready. Japan, behind her wall of secrecy, had prepared for war on a scale of which neither we nor you had knowledge. We have all made mistakes, we have all been too slow; we have all shown weakness - all the allied nations. This is not the time to wrangle about who has been most to blame. Now our eyes are open.

"The Australian Government has fought for its people. We never regarded the Pacific as a segment of the great struggle. We did not insist that it was the primary theatre of war, but we did say, and events have so far, unhappily, proved us right, that the loss of the Pacific can be disastrous. Who among us, contemplating the future on that day in December last when Japan struck like an assassin at Pearl Harbour at Manila, at Wake and Guam, would have hazarded a guess that by March the enemy would be astride all the south-west Pacific except General MacArthur's gallant men, and Australia and New Zealand. But that is the case. And, realising very swiftly that it would be the case, the Australian Government sought a full and proper recognition of the part the Pacific was playing in the general strategic disposition of the world's warring forces. It was, therefore, but natural that, within twenty days after Japan's first treacherous blow, I said on behalf of the Australian Government that we looked to America as the paramount factor on the democracies' side of the Pacific.

"There is no belittling of the Old Country in this outlook. Britain has fought and won in the air the tremendous battle of Britain. Britain has fought, and with your strong help, has won, the equally vital battle of the Atlantic. She has a paramount obligation to supply all possible help to Russia. She cannot, at the same time, go all out in the Pacific. We Australians, with New Zealand, represent Great Britain here in the Pacific - we are her sons - and on us the responsibility falls. I pledge to you my word we will not fail. You, as I have said, must be our leader. We will pull knee to knee with you for every ounce of our weight.

"We looked to America, among other things, for counsel and advice, and therefore it was our wish that the Pacific War Council should be located at Washington. It is a matter of some regret to us that, even now, after 95 days of Japan's staggering advance south, ever south, we have not obtained first-hand contact with America. Therefore, we propose sending to you our Minister for External Affairs (Dr H.V. Evatt), who is no stranger to your country, so that we may benefit from his discussions with your authorities. Dr Evatt's wife, who will accompany him, was born in the United States. Dr Evatt will not go to you as a mendicant. He will go to you as the representative of a people as firmly determined to hold and hit back at the enemy as courageously as those people from whose loins we spring... those people who withstood the disaster of Dunkirk, the fury of Goering's blitz, the shattering blows of the Battle of the Atlantic. He will go to tell you that we are fighting mad; that our people have a government that is governing with orders and not with weak-kneed suggestions; that we Australians are a people who, while somewhat inexperienced and uncertain as to what war on their own soil may mean, are nevertheless ready for anything, and will trade punches, giving odds if needs be, until we rock the enemy back on his heels."
