Problem: The war is portrayed in Mikhail Bulgakov's novel The White Guard. Many folk songs were written from 1918 to 1922 that were inspired by people and events of this conflict. "Oi u luzi chervona kalyna" and "Oi vydno selo" were inspired by the Ukrainian Sich Riflemen unit of the Austro-Hungarian Army, which became the core battalion of the West Ukrainian People's Republic's Ukrainian Galician Army. "Pisnya pro Tiutiunnyk" was inspired by events surrounding Ukrainian People's Army brigade commander Yuriy Tiutiunnyk. Another song written at this time was "Za Ukrayinu". These "war songs" started to be sung publicly again in the western part of the Ukrainian SSR after the introduction of glasnost by Soviet leader Mikhail Gorbachev, and regained popularity throughout Ukraine after independence - especially during the current Russian military intervention. Another musical legacy of this period was the Ukrainian Republic Capella , set up in early 1919 by the Directorate government of Symon Petliura. Under the direction of Oleksandr Koshetz, the Capella/Chorus toured Europe and North America from 1919 to 1921 and while in exile from 1922 to 1927; popularising the songs "Shchedryk" and "Oi khodyt son, kolo vikon" - which influenced the composition of the popular English language songs "Carol of the Bells" and "Summertime", respectively. In the 21st century the Kholodny Republic flag was seen during the Euromaidan demonstrations and was later used by the Azov Battalion in the War in Donbas.

Problem: In 1990 just over half the cocaine imported into the U.S. came through Mexico, by 2007 that had risen to more than 90 percent, according to U.S. State Department estimates. Although violence between drug cartels has been occurring long before the war began, the government used its police forces in the 1990s and early first decade of the 21st century with little effect. That changed on December 11, 2006, when newly elected Mexican President Felipe Calderon sent 6,500 federal troops to the state of Michoacan to put an end to drug violence there. This action is regarded as the first major retaliation made against cartel operations, and is generally viewed as the starting point of the Mexican Drug War. As time progressed, Calderon continued to escalate his anti-drug campaign, in which there are now well over 25,000 troops involved. During the Felipe Calderon, the Mexican government has spent approximately US$7 billion in an 18-month-old campaign against drug cartels. It is estimated that during 2006, there were about 2,000 drug-related violent deaths, about 2,300 deaths during 2007, and more than 6,200 people by the end of 2008. Many of the dead were gang members killed by rivals or by the government, some have been bystanders.

A: 4200

Problem: The heavy French losses at the Battle of Gaouz encouraged an increase in tribal activity across the south-east of Morocco, threatening the French presence at Boudenib. Poeymirau was forced to withdraw garrisons from outlying posts in the Tafilalt, including that at Tighmart, to concentrate his force and reduce the risk of further disasters. Lyautey authorised only a series of limited offensives, such as the razing of villages and gardens, the primary aim of which was to emphasise French military superiority. The French struggled to move troops through the mountain passes from the Moulouya Valley due to heavy snows and attacks on their columns, and Lyautey, to his embarrassment, was forced to request reinforcements from Algeria. By October the situation had stabilised to the extent that Poeymirau was able to withdraw his troops to Meknes, but a large-scale uprising in January 1919 forced his return. Poeymirau defeated n'Ifrutant in battle at Meski on 15 January, but was seriously wounded in the chest by the accidental explosion of an artillery shell and was forced to hand command to Colonel Antoine Hure. Lyautey then received assistance from Thami El Glaoui, a tribal leader who Lyautey had made Pasha of Marrakesh after the uprising of 1912. El Glaoui owed his increasing wealth to corruption and fraud, which the French tolerated in return for his support. Thus committed to Lyautey's cause, El Glaoui led an army of 10,000 men, the largest Moroccan tribal force ever seen, across the Atlas to defeat anti-French tribesmen in the Dades Gorges and to reinforce the garrison at Boudenib on 29 January. The uprising was over by 31 January 1919.
