When one Republican presidential candidate for the 2016 election ridiculed the liberalism of "New York values" in January 2016, Donald Trump, leading in the polls, vigorously defended his city. The National Review, a conservative magazine published in the city since its founding by William F. Buckley, Jr. in 1955, commented, "By hearkening back to New York's heart after 9/11, for a moment Trump transcended politics. How easily we forget, but for weeks after the terror attacks, New York was America."
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In what year was the National Review founded?
Ah, so.. 1955

Russia feared losing Russian America without compensation in some future conflict, especially to the British. While Alaska attracted little interest at the time, the population of nearby British Columbia started to increase rapidly a few years after hostilities ended. Therefore, the Russian emperor, Alexander II, decided to sell Alaska. In 1859 the Russians offered to sell the territory to the United States, hoping that its presence in the region would offset the plans of Russia's greatest regional rival, the United Kingdom.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who is Russia's largest regional rival?
Ah, so.. the United Kingdom

Ban Chao (d. AD 102) enlisted the aid of the Kushan Empire, occupying the area of modern India, Pakistan, Afghanistan, and Tajikistan, to subdue Kashgar and its ally Sogdiana. When a request by Kushan ruler Vima Kadphises (r. c. 90c. 100 AD) for a marriage alliance with the Han was rejected in AD 90, he sent his forces to Wakhan (Afghanistan) to attack Ban Chao. The conflict ended with the Kushans withdrawing because of lack of supplies. In AD 91, the office of Protector General of the Western Regions was reinstated when it was bestowed on Ban Chao.

Ah, so..
Vima Kadphises
