Sounds to me like a slow descent into the nether world of the liberals. If a class cannot be completed in one year (as history, geography, etc), then it should be taught in two years.
One of the mysteries to me is why when we teach US History we do not teach enough World History to explain the correlation between the two. What was going on in England and France when the US was fighting the French and Indian War? What happened in Europe just prior to the US Civil War that influenced it? Instead of teaching US History in 11th grade and World History in 12th, combine the two and teach History 1 in 11th and History 2 in the 12th.

The world history you cited focuses on Western Europe, for good reason. The United States is a Western nation whose history is intertwined with England and to a lesser extent the other countries of Western Europe. Acknowledging the special debt that America owes to its English heritage is an offense against multiculturalism and is not politically correct.
My parents are from India. India as a nation dates only to 1948, but the recorded history of people living in what is now India goes back for millenia (as it does for China). However, the history of India and China are less important for understanding American history. That should be obvious, but for many educators that statement borders on “racism”.
Fairfax VA public schools sort of align with your ideas. College-bound students in the sixteen "AP" high schools [there are also eight International Baccalaureate (IB) high schools] can take "honors" World Civ in 9th grade. They spend the year covering up to the beginning of the Renaissance. These students pick up the rest of world history in "AP World Civ" in 10th grade and take the AP World Civ test at the end of their sophomore year. Juniors take AP US History, and seniors take AP Government.
Four Fairfax high schools (all of them AP schools) were just rated in the top hundred US high schools by US News and World Report. That magazine uses methodology developed by School Evaluation Services and criteria include college readiness, proficiency on standardized state tests, and student participation in and performance on Advanced Placement (AP) and (IB) exams.
Thomas Jefferson, a Fairfax County public high school with very tough competitive admission, is ranked #1 in the nation. Of the other three Fairfax high schools in the top hundred, McLean and Langley are in the wealthy part of the county, while Woodson High School has more "typical" demographics and also hosts the largest Special Ed Center in the county. The average number of AP courses taken by all Woodson students by the time they graduate is more than three.
