It would have been years of trench warfare until one side gave up.
Hmmm...Germany gave up
German territory was never invaded by the Allies.
The thousands of ANZACs being wasted to do the bidding of the Imperial whip infuriated many.
Oh really?! The ANZAC Corps was an all-volunteer formation. The Australian population, while independent since 1901 was still very much a part of the Empire culturally, and the pound remained as currency into the 60s. There was no talk of the 'Imperail whip' in Australia that I know of, and opponents to war were seen as traitors and Communists. The Corps represented the entire cross-section of Australian and New Zealand society from politicians to labourers, and public servants to farmers. Only towards the end of the war was conscription seen as something that may be required because the contribution of Australia and New Zealand to the war far exceeded what could have been expected from an all-volunteer forces considering the population sizes they came from.
Was the US Army all volunteer?

They Answered the Call
Military Service in the United States Army During World War I, 1917-1919
By Mitchell Yockelson
More than 24 million men registered for the draft, and almost 2.7 million men were furnished to the U.S. Army by conscription. The number of volunteer enlistments was slightly over 300,000. The US Regular Army numbered about 200,000 in 1917.
Now consider this figure:
For Australia, as for many nations, the First World War remains the most costly conflict ever in terms of deaths and casualties. From a population of fewer than five million, 300,000 men enlisted, of which over 60,000 were killed and 156,000 were wounded, gassed or taken prisoner.
http://www.awm.gov.au/atwar/ww1.htm
Australia total served 330,000, 59,000KIA, 152,000WIA, total 211,000 (64%)
New Zealand served 110,000, 18,000KIA, 55,000WIA, total 73,000 (66%)
So how is it that US suffered double the Australian casualties in such a short time. It seems you are using selective sources. Consider this:
53,402 KIA + 63,114 other deaths = 116,516 (DoD; 1991)
126,000 (S&S; Eckhardt)
USA* served 4,272,500 (includes Navy and Marines), 117,000 (given as KIA but note above) 204,000 (non-combat related) total 321,000 (8%)
So in the few months of WW1 at its end US suffered 53,402 KIAs. How? Well, even this figure can be further understood by looking at this table
Cause of Death Overseas Domestic Total
Killed in Action 36,926 5 36,931
Died of Wounds 13,628 45 13,673
Died of Accident 2,557 1,946 4,503
Drowned 328 399 727
Committed Suicide 296 671 967
Murdered 159 159 318
Executed 11 25 36
Other Deaths 131 190 321
Total 54,036 3,440 57,476
So the actual combat loss should be 50,604. However the American Battle Monuments Commission "only have records of those casualties that are buried in our cemeteries or listed on the Walls of the Missing -- a total of 33,717 records." This is lower then even the KIA figure.
Why did US troops suffered such high casualties in the little time they spent in combat? Pershing ordered the use of frontal assaults, which had been discarded by that time by British Empire and French commanders because of the large loss of life sustained throughout the war.
Here is a very brief look at casualties in perspective of the timeline of last few months of the war.

Of course you may want to challenge this finding with your own figures.
