So, as the title says, the Drakaverse United States and Third Reich from their ATL's December 1st, 1941 is ISOTed in place of our own. As the map shows, both are behemoths, with the resources and industry to match it. The United States spans all of continental North America, as well as Cuba, the Philippines, Hawaii, Haiti, and Santo Domingo (OTL Dominican Republic).
The population by 1940 is 179,000,000 and thus effectively equal to that of the USSR in OTL 1941. For an idea of what the lead up and early "Eurasian War" (their analogue of WWII) has been like,
here is from the official timeline:
1930 -Stock market crisis leads to mild but chronic recession outside Domination. First chain reaction observed. Closed-circuit television.
1932 -Hitler elected with majority in Germany. F.D. Roosevelt elected President in U.S.; declares "New Deal" for lower classes, Hispanics, etc. Limited recovery.
1936–37 -Civil war in Spain; defeat of Nationalists by 1937. Soviet Republic of Spain established. Germany takes Austria. French and British abandon Czechoslovakia; Sudeten War follows. Clashes on Draka–Japanese and Draka–Soviet borders. Experiments with electrodetection (radar) in several countries. Domination begins long-term project to harness nuclear energy. Albert Einstein, Enrico Fermi move to U.S.
1939 -France and Britain guarantee Poland. Eurasian War begins. Nazi–Japanese alliance. Transistor invented in Toronto, State of Ontario. First commercial tape recorder.
1940 -Fall of France. Battle of Britain ends in stalemate; Nazi submarines effectively close Atlantic. Japanese aggression in Southeast Asia produces severe tension with U.S., Australasian Federation.
1941 -Domination attacks Italy with tacit consent of Germany. Germany attacks and defeats Soviet Union. Moscow falls October 1; Germans reach Urals and Caucasus by first snow. Imperial Japan attacks U.S. on December 3rd, occupies eastern Siberia, destroys entire American Pacific Fleet in Pearl Harbor. Hawaii, Philippines overrun, West Coast raided, landings made in Panama. U.S. declares war on Japan and Germany.
As noted earlier, this ISOT occurs on December 1st so the Pacific Fleet remains intact while the Germans have already long since effectively beat the Soviets. Military technology is also quickly advancing in this timeline, and no doubt would continue here:
Technological developments 1940–1943: millimetric wave radar. Reaction-jet fighters in Domination, Germany, U.K., U.S. Helicopters deployed for observation, casualty evacuation by Draka, U.S., Germany. Draka test prototype tiltrotor VTOL transport, VTOL jet with plenum-chamber boost. Fuel-cell powered submarines by Germany, U.S. All-transistor programmable digital computer (U.S., 1943); first nuclear power reactors, plutonium (Domination 1941, U.S. 1942). Long-range liquid fuel rockets, Germany. Television-guided glide bombs, radar-guided cruise missiles (U.S. Both crude, but useable.)
For some more detailed differences in economics, general technology and culture, see here:
- Steam transport got under way about a generation earlier than in our history, and steam cars have been common since the 1820's, gradually improving. By the time the internal combustion engine came along, so much effort had gone into developing automotive steam engines that they remained dominant in all but aeronautical and armored fighting-vehicle applications. Petroleum or coal oil has been the dominant fuel for autosteamers since the first Egyptian oil fields were discovered (by teams drilling for water) in the 1810's. Modern (1940) autosteamers have pressure-injected flash boilers with high superheat, operating safely at 1,200 psi; the standard operating unit is a triple-expansion uniflow with extensive electric auxiliaries. Heavy, articulated trucks are common, particularly in the Domination. The autosteamers of the 40's represent a "mature" technology—fairly uniform everywhere, rugged, easy to maintain and very long-lasting. Performance and price are both lower than the equivalent internal-combustion machines of our history, but reliability is greater. Since they are relatively simple to manufacture, most nations with any pretensions to modernity have an autosteamer industry.
- Air transport became a practical reality in the 1870's; the Domination's need for fast long-distance transport provided the incentive. The first dirigibles were steam-turbine powered, with laminated wood frames and cloth hull coverings. By 1914, "metalclad" airships were the rule (a thin metal hull providing gas sealage, with an internal frame). Size had increased to 1,000 feet length, 250 feet maximum diameter, 8,000 mile range and 100 tons useful lift, burning a mixture of kerosene and hydrogen as fuel. Heavier-than-air planes were developed primarily to destroy dirigible bombers, and did so very effectively. Transport dirigibles continued in use, and by the 1940's could carry up to 200 tons for 12,000 miles at 90 mph. Long distance air freight dates from the 1890's (the decade of the first Atlantic crossing). The more primitive areas of the continental interiors were largely opened up by dirigibles: Yunnan, Tibet, the New Guinea highlands…
- Urban mass transit got an earlier start, since the autosteamer could be employed on city streets. Monorails evolved from elevated urban railways—first pneumatic, then electric, then powered by linear induction motors. Autosteamers and trucks served as feeders to railways from the beginning, ousting animal transport very gradually over a period of generations—first in the advanced countries, and spreading from there.
- "Modern" (Bauhaus) architecture never really got under way in the Domination's timeline; Frank Lloyd Wright practiced, but the German school was never born. Steel-frame and ferroconcrete construction are common, but the unadorned "glass shoebox" is reserved for industrial uses. Public and domestic architecture in the Domination is predominantly "Drakastyle"—an Art-Nouveauish version of earlier Classico-Mughal schools: lines are fairly simple, but with elaborately decorated surfaces (mosaic, murals, stained glass). Euro-American styles are variously historic, Art Nouveau-Art Deco, and "Mechanist." Skyscrapers are common in the larger American cities, but not much imitated elsewhere. Central air-conditioning was developed in the Domination in the 1850's, immediately after the invention of practical refrigeration, and spread rapidly to the tropical areas of the U.S.; small, single-dwelling units were available in America by the time of the Great War.
- Clothing makes less use of synthetic fabrics, since the natural equivalents are much cheaper than in our history. Draka clothing adapted early to tropical climates; it is loose, light, and nonconfining. This has had some influence on general Western, styles. Trousers for women were introduced for sporting purposes in the Domination in the 1860s, and for casual wear in "daring" circles by about 1900. The U.S. followed about a generation behind, and Europe still later. Hats remain common for both sexes past the 1950's; colors are usually brighter.
- Social intoxicants have a rather different history in the Domination's timeline. Both the United States and the Domination are exposed to cannabis on a large scale fairly early—the Draka from the North Africans and the U.S. from Mexico. Sporadic attempts at prohibition in the United States break down in the 1930's, with social acceptance (outside the Bible Belt) following during the Eurasian War. (In the process, ethnic Mexicans come to dominate organized crime in most major cities, much to the discomfort of the law-abiding majority of Hispanics.) Ganja is popular and legal in the Domination from the early nineteenth century; both countries launch occasional educational campaigns to prevent abuse. The first studies linking tobacco to cancer and heart disease are done in Germany in the 1930's and at first, widely discounted as Nazi propaganda. The U.S. is otherwise a spirits-and-beer country, with some wine-drinking enclaves. The Domination is a wine-and-brandy region with a minor key in (German and Scandinavian-influenced) beer.
- Solar-power units (glass circulating-water collectors, with underground pressurized-water heat sinks) were developed for isolated plantations in the Domination in the 1860's, and spread widely in high-sunlight tropical regions. By the 1920's most ranches and farms in the American Sunbelt have one.
- Household appliances (vacuum cleaners, etc.) are primitive, and outside the U.S. rare.
So, what happens from here?
