This is a good overview of America during WWI. It has too much focus on Woodrow Wilson (which shouldn't be too surprising given that the author serves on the advisory council of the Woodrow Wilson House in DC). There didn't seem to be much original analysis here, but mostly a retelling of the war. It did a decent job at that at least. It does cover a lot of ground, ranging from the road to war, the home front, the battle front, the peace negotiations, and adjusting to the post-war age. The best parts were those on the homefront, but the early phases and the (too long) discussion of the peace negotiations were less notable.
Some things I got from the book: Wilson's initial reaction to the Luisitania was basically to shrug it off. The national reaction forced him to do more. The shift toward preparedness was pitched as a way to keep us out of war, but it angered pacifists. A bomb went off in a Preparedness Day Parade in San Francisco. The US army had just 92,482 on active duty in 1914, but May 1916 saw legislation to double the army to a half-million by 1921 (I guess it grew a lot from 1914-16 then). In July 1916, the UK blacklisted 82 US companies due to German trade. There were some dynamite bombs in NYC & DC - apparent German sabotage. The biggest explosion occurred on July 30, 1916 - blowing up a big munitions depot in Jersey City. The blast was felt in multiple states and damaged the Statue of Liberty's upper arm. Garrett Peck also argues that 1916 was the first modern election with opposition research, targeted advertising, and using the mass media. Then Germany went back to submarine warfare in 1917 and the Zimmerman Telegram made a big impact. The first American vessel sunk without warning was the Algonquin on March 12. Then came five more by April 1. The war vote was 82-6 and 373-50.
The army lacked manpower, firepower, tanks, aircraft and combat doctrine for modern war. Dog tags were new to this war. The US budget was $742 million in 1916 but $14 BILLION by 1918. The debt ceiling was created for the war. The top tax, initially just 7% went up to 65% in 1917 and then to 77% in 1918. Daylight savings began as fuel conservation. Unions gained strength as Wilson was pro-labor. Racial violence broke out in East St. Louis and against soldiers in Houston. Wilson was given power over food supplies, and appointed Hoover over the Food Administration. The Shipping Board was created to help make sure that worked. German sailors (here for trade when all hell broke less) were put in internment camps. An Executive Order dealt with German aliens here. Travel was forbidden without approval for them and they were not allowed in key areas of the nation, like DC. The values of democracy were undermined.
The AEF had just 14,000 troops and were poorly trained. Germany had laid some mines even by the US. Pershing comes off poorly. He believed in the importance of the rifle and individual soldiers moving on open fields. He ignored Allied officers who knew better. His generalling led to needless US deaths. There were 367,000 black soldiers, of whom 200,000 went to France, but just 50,000 saw action. It was illegal to give booze to a soldier in uniform. There were heavy US losses at the Battle of Soissons. At the 2nd Battle of the Marne, the US suffered 50,000 casualties out of 300,000 fighting. Influenza began in Kansas in January 1918 and left 21 million dead. The big allied offensive of 1918 began on Sept. 26. The Meuse-Argonne was the largest US offensive in history (not clear if he means up until then or even if you include WWII).
Wilson didn't want any GOP'rs going to Versailles, so they didn't. Wilson left for six months (he came back briefly midway through) and thus lost much ability to shape public opinion. William Howard Taft supported the League of Nations idea, but Wilson did a bad job pitching his idea, being too condescending to those who disagreed with him. Then he had a stroke, and was basically a lame duck for the last year and a half of his presidency.
1919 saw race riots. Wilson didn't get involved in that as he focused on Versailles. He also sat out the prohibition debate (which splits his party's northern/southern wings) as it was divisive - and that's especially bad since it heated up during the war). There was the Red Scare and bombs and anarchists upset at the deportation of Luigi Galleani. Wilson came out in favor of women's suffrage, largely due to the war. 5,000 Germans were interned in camps, which isn't as big as the 120,000 Japanese-Americans there in WWII, but still a black eye.
The book is often more critical of Wilson than I'd guess given Peck's place on the Wilson House advisory board, but it still doesn't have much clear opinion on matters, mostly just sticking to narrative.
