Grfh, your understanding of The United States from 1900 to 1918 is completely and utterly wrong. This isn't a matter of conflicting opinions, it's that your facts are not correct.
I believe that what you're doing is applying today's standard of "debtor nation" to America as a "debtor nation" in 1900 - 18. Yes, the U.S. was a debtor nation in that period, but the debt was being used to finance expansion and industry. America wasn't borrowing money to prop up an unstable government or maintain a military or navy, it was using investment funds to grow the industrial base with a healthy return on investment. FPI and FDI was at an all time high because the economy was robust, not exhausted. In 1914, America had the highest per capita percentage of any nation of the world - $5,000. per head of household, compared with $1500. per head of household in Russia. In 1903 our agricultural sales reached $3Bil per year and continued to maintain that level and surpass it until 1918. In 1914, we were the third largest exporter of steel, behind Great Britain and Germany. In 1914, we were one of the world's largest exporters of raw material, by 1918, we were the largest exporter of finished goods. Life expectancy from adulthood was 72 yrs.
We had built the Panama Canal, Pres. T.R. had brokered the peace in the Russo-Sino war and had the second largest navy in the world.
In one post you claim that the United States was the world's leader in armaments, and yet in this last post, you claim that the U.S. did almost nothing to advance the military cause of the allies. Of course, neither claim is correct. The U.S. was the third largest exporter of armaments, and from the first deployment of 85,000 troops in March of 1918, by September of 1918 they had trained, equipped and transported over 1,200,000 men to an overseas theater of war. Did the United States build battle ships during this period? They didn't have to, they didn't need them. What they did need were destroyers, and 35 new destroyers had been deployed by 1917, with 380 new submarine chasers and armed merchant ships already stationed overseas. U.S. troops were not going without food and shelter, they were going without army food and shelter, simply because the influx of draftees were swelling ranks faster than they could be supplied and transported. No draftees went without food and shelter at any time, because of the high public commitment to the war effort. Local communities were sheltering and feeding draftees which were overflowing army training facilities. The railway system wasn't broken down, it was overused - railway companies could not keep up with industrial and goverment demands. The claim that the U.S. mobilization was almost a disaster and ended with an "economic dictator" borders on the ridiculous. In fact, Barush as head of the wartime commission, rarely, if ever used any kind of legislative action, to push government contracts ahead of private industry contracts. He cajoled and at a last attempt threatened public humiliation which was generally enough to re-organize production schedules in the government's favour.
As to food production, Hoover wasn't recommending "meatless Mondays" because Americans didn't have food, he was recommending it to feed the Belgians and French caught between the allies and the central powers. (In fact, in the history of the United States, there has never been a famine.) This was accomplished without rationing, and by a government guarantee of payment per bushel. In fact, by 1918, the United States was the world's largest manufacturer of finished foodstuffs This is not because of the precipitous drop in European food production as much as it was the labour cost ratio of crops planted by U.S. farmers. Because of our early mechanization of farming, one farmer in the United States could plant and harvest a hundred acres (and did) where in other countries the labour ratio was at least two men per ten acres and in Russia was often one man per acre harvest of wheat.
In medicine, by 1886, Bellevue Hospital School for Nurse's training had been established. In 1901 the Army Corps of Nurses had regularly been training nurses as had The American Red Cross. Compared to today's standards, all medical practice at the turn of the century was primitive, but the fact that Americans had the longest rate of longevity in the world, would belie the claim that Americans were suffering from poor health.
I don't understand why there must be an adversarial comparison to Russia. I also don't understand how you can claim in one post that Americans were in the position to dictate the fate of the Romanovs and in the next post claim that the United States was a third world primitive backward nation, incapable of contributing to the allied cause.
