Problem: Alsace:

Holy Roman Empire central power had begun to decline following years of imperial adventures in Italian lands, often ceding hegemony in Western Europe to France, which had long since centralized power. France began an aggressive policy of expanding eastward, first to the rivers Rhône and Meuse, and when those borders were reached, aiming for the Rhine. In 1299, the French proposed a marriage alliance between Philip IV of France's sister Blanche and Albert I of Germany's son Rudolf, with Alsace to be the dowry; however, the deal never came off. In 1307, the town of Belfort was first chartered by the Counts of Montbéliard. During the next century, France was to be militarily shattered by the Hundred Years' War, which prevented for a time any further tendencies in this direction. After the conclusion of the war, France was again free to pursue its desire to reach the Rhine and in 1444 a French army appeared in Lorraine and Alsace. It took up winter quarters, demanded the submission of Metz and Strasbourg and launched an attack on Basel.

When was Alsace charted by the Counts?

Problem: With its myriad islands, Alaska has nearly 34,000 miles (54,720 km) of tidal shoreline. The Aleutian Islands chain extends west from the southern tip of the Alaska Peninsula. Many active volcanoes are found in the Aleutians and in coastal regions. Unimak Island, for example, is home to Mount Shishaldin, which is an occasionally smoldering volcano that rises to 10,000 feet (3,048 m) above the North Pacific. It is the most perfect volcanic cone on Earth, even more symmetrical than Japan's Mount Fuji. The chain of volcanoes extends to Mount Spurr, west of Anchorage on the mainland. Geologists have identified Alaska as part of Wrangellia, a large region consisting of multiple states and Canadian provinces in the Pacific Northwest, which is actively undergoing continent building.
What do geoligists believe isn't unique about Wrangellia?

Question: On 7 August 1998, al-Qaeda struck the U.S. embassies in Kenya and Tanzania, killing 224 people, including 12 Americans. In retaliation, U.S. President Bill Clinton launched Operation Infinite Reach, a bombing campaign in Sudan and Afghanistan against targets the U.S. asserted were associated with WIFJAJC, although others have questioned whether a pharmaceutical plant in Sudan was used as a chemical warfare plant. The plant produced much of the region's antimalarial drugs and around 50% of Sudan's pharmaceutical needs. The strikes failed to kill any leaders of WIFJAJC or the Taliban.
