From an alternate reality, I'll ask three questions of your reality and you can ask three for mine

Sure.  Why not.

Mittelafrika was a concept after the first World War, where Germany would've taken all of France's colonies at the Treaty of Versailles, but at the time, the Americans and Confederates agreed that Germany would only take Ivory Coast, French Congo, and Central Africa, making Kamerun somewhat larger as it remains to this day.  In my reality, Kamerun is a German speaking nation, as is the nation that calls itself die mittelafrikanische Republik.  Instead, France maintained only a few of its colonies in Africa, and one or two in Asia, but the rest were yielded to the League of Nations, then to Germany and the UK.

The War for Southern Independence was successful only because the Confederates followed the Cleburne Memorial and enlisted and freed their bonded Africans beginning in 1864.  That enabled them to overcome the manpower problem as well as gain foreign recognition which helped ease the food and medicine problem they had been facing due to the Union blockade.  Once they gained independence, they began to industrialize themselves to avoid dependence on the Yankees, and their use of profit-sharing (an idea proposed by Jefferson Davis), avoided the rise of any form of socialism or communism.  Without the Yankees telling them what to do after the war, the Confederates managed bringing their bonded Africans into independence on their own terms within ten years, while full civil rights took a few more decades, when the 1896 voting rights act allowed them to vote in confederal elections, while the states took a little while longer.  

Lincoln didn't die during or after the war, but was impeached in 1867 when the Northern Democrats took back the House and nearly took back the Senate, for a host of war crimes - suspending habeas corpus, shutting down newspapers, jailing people who disagreed with him, arresting members of the Maryland legislature, starting a war without a declaration of war by Congress, conspiring to start a war at Fort Sumter, and then not calling Congress for three months to ensure a war would start.  Johnson took his place, but he was soon replaced by Grant, a war hero.

The Union offensive was pushed back at Atlanta, when Joseph Johnston defeated General Thomas at Peachtree Creek (mostly due to General Cleburne and his 30% black force).
General Lee led the Army of Northern Virginia, with JEB Stuart, who later became a railroad executive, James Longstreet, whose son became President of the CS, and Thomas 'Stonewall' Jackson, whose son also became President, and he also created the Confederate Military Institute, which transformed military doctrine in the South.  We later absorbed part of Mexico in 1867 in exchange for the French leaving, giving us Rio Grande, Sonora, Washington, Veracruz, Jefferson, and Durango state.  The same year we bought Alaska from the Russians, since the Americans were otherwise occupied at the time with impeachment.  In 1874, we had the Spanish-Confederate War, gaining Puerto Rico, Cuba, the Mariana Islands, and the Philippines, and also annexed Hawaii by their request after a joint British-American military invasion.  In 1915 we bought the Danish Virgin Islands, and in 1917, the British Virgin Islands and the Bahamas for some debt forgiveness, and from the French, we claimed and acquired Martinique, Guadeloupe, French Guyana, New Caledonia, Polynesia.  As of 1976, we have 34 states in the Confederacy: Virginia, Kentucky, Tennessee, North and South Carolina, Georgia, Alabama, Mississippi, Florida, Arkansas, Louisiana, Texas, Oklahoma, New Mexico, Arizona, California (along the same 37th parallel as AZ, NM, and OK), Washington (formerly Chihuahua), Sonora, Rio Grande, Durango, Veracruz, Jefferson, Cuba, Puerto Rico, Virgin Islands, Bahamas, Martinique, Guadeloupe, Guyana, Alaska, Hawaii, Polynesia, Mariana Islands, and New Caledonia.  The country is 257 million people, and is about 73% white, 18% black, 4% Native Confederate, 4% Asian, and the rest are other ethnicities.

I live in these Confederate States, whose President today is a relatively young-looking 53-year-old Asian Confederate, James Yen.  We've had three black VPs, two women VPs, two black Presidents, and two women Presidents, plus one Asian-Confederate President.  Our last 3 presidents were Hank Rogers (C), Jessica Howard (C), and then James Yen (R).  President Yen is our 27th President since President Davis.  We have 3 main parties now, the Confederate, Democrat, and Republican.  Unlike the US, the Democrat party is not a socialist party, but is more agrarian and small government, the Confederate party is similar but focuses on our unique Confederate heritage, while the Republican Party, formed from elements of both parties who thought that after the second world war, we needed to become more internationally active to maintain peace with the Soviet Union looming.  After the fall of communism, we did help East and West Poland reunite, Volgaland modernize, we helped chair the Treaty of Constantinople in 1993 in Greece which stopped the North and South Turkish War, and the Treaty of Nashville in 1993 which resolved the Azerbaijani-Armenian War.

Our taxes are also much lower than the Union, since most states don't have income taxes, and we have no confederal income tax, and no welfare system.  The closest we have is the annual sovereign wealth fund, which pays out for oil and mineral resources extracted from a given state, which automatically goes into our individual retirement accounts (IRAs), and we can deduct parts of our paychecks for retirement, disability, unemployment, and medical issues.  The Confederate Dollar is two or three times more valuable than the Union dollar, but their dollar has stabilized since the 1980s.  We've also seen a lot of disturbing news from the Union regarding corruption, children, and international corruption, but I'll leave that alone.

In my reality, there is a relatively obscure German painter who died in WW1 by that name, but he isn't really all that important except to art history students in Germany who seem to enjoy his relatively simplistic art, as if it tells of his alienation or something.
