Alexander II (Russian: Aleksandr II Nikolaevich, tr. Aleksandr II Nikolaevich; IPA: [aljI'ksandr fta'roj njIka'lajIvjItc]; 29 April [O.S. 17 April] 1818 in Moscow - 13 March [O.S. 1 March] 1881 in Saint Petersburg) was the Emperor of Russia from 2 March 1855 until his assassination in 1881. He was also the King of Poland and the Grand Duke of Finland. Alexander was the most successful Russian reformer since Peter the Great. His most important achievement was the emancipation of serfs in 1861, for which he became known as Alexander the Liberator (Russian: Aleksandr Osvoboditel', tr. Aleksandr Osvoboditel; IPA: [aljI'ksandr asv@ba'djitjIlj]). The tsar was responsible for numerous other reforms including reorganizing the judicial system, setting up elected local judges, abolishing capital punishment, promoting local self-government through the zemstvo system, imposing universal military service, ending some of the privileges of the nobility, and promoting the universities. Despite these reforms, during his reign, his brutal secret police, known as the Third Section, sent thousands of dissidents into exile in Siberia. In foreign policy, Alexander sold Alaska to the United States in 1867, fearing the remote colony would fall into British hands if there was another war. He sought peace, moved away from bellicose France when Napoleon III fell in 1871, and in 1872 joined with Germany and Austria in the League of the Three Emperors that stabilized the European situation. Despite his otherwise pacifistic foreign policy, he fought a brief war with Turkey in 1877-78, pursued further expansion into Siberia and the Caucasus, and conquered Turkestan. Although disappointed by the results of the Congress of Berlin in 1878, Alexander abided by that agreement. Among his greatest domestic challenges was an uprising in Poland in 1863, to which he responded by stripping that land of its separate Constitution and incorporating it directly into Russia. Alexander was proposing additional parliamentary reforms to counter the rise of nascent revolutionary and anarchistic movements when he was assassinated in 1881. <sep>Why is Alexander II called Aleksandr Osvoboditel?<sep>Because he captured Poland

This week, we've been treated to the increasingly familiar sight of former NBA star and provocateur Dennis Rodman attending events in Pyongyang, North Korea. It's his fourth trip in less than 12 months. On Tuesday, an angry Rodman defended his visit in a CNN interview straight from Pyongyang, at one point saying to "New Day" anchor Chris Cuomo, "I don't give a rat's ass what the hell you think ..." in response to question about Kenneth Bae, an American detained in North Korea. When will we tire of this circus? In case you don't watch cable news, you might miss that the media really loves this kind of thing. No story about North Korea is too weird to go unreported, even if there is no real information to disseminate. Recall the recent rumor that Kim Jong Un's uncle was executed by being fed to hungry dogs, which most likely was started as satire on Chinese social media but was at first reported widely in the media (CNN was unable to confirm and did not report the story). In media discourse, North Korea is the classic enemy. The regime's injustices, quirks and dysfunctions are reassuring to Americans that their own country is just the opposite: Normal, well-functioning, a land of peace and liberty. But add in Rodman to the North Korea story, and it's bound to produce eye-popping headlines: The Weird American Athlete Goes to Weird Country story is just too easy not to cover. Rodman himself seems to be thriving on finding a strange smidgen of relevance through his visits to North Korea (and perhaps a Paddy Power paycheck). Though often described as quite shy, he has always enjoyed challenging the values of Middle America. North Korea is providing him a new avenue to be in the spotlight. The most passive player in this tragicomedy is Rodman's home country, the United States. The U.S. State Department has deployed the rhetorical equivalent of an embarrassed teenager whose dad has shown up to dance at his prom. Something along the lines of "this has nothing to do with us" is what the State Department has said with every one of Rodman's trip. Last winter,the State Department criticized Rodman's timing as it followed a nuclear test and rocket launch. <sep>What makes the story of Rodman in North Korea notable?<sep>His odd hair color attracts attention

In Colombia, the drug-financed guerrillas trying to seize the country and destroy democracy include M-19, which Castro has clearly backed. Robert Merkel, a former U.S. attorney handling drug indictments in Florida, doesn't think for a minute that Castro's much publicized trials of high officials engaged in the drug trade mean he has broken off with the Medellin drug cartel. "If the cartel succeeds in blackmailing the Colombian authorities into negotiations, the cartel will be in control and Fidel can exploit his past relationships with them," he told the Journal's David Asman recently. The struggle against the drug lords in Colombia will be a near thing. This week, the government arrested Jose Abello Silva, said to be the fourth-ranking cartel leader. He will probably be extradited to the U.S. for trial under an extradition treaty President Virgilia Barco has revived. Later, another high-ranking trafficker, Leonidas Vargas, was arrested and 1,000 pounds of dynamite seized. Mr. Barco has refused U.S. troops or advisers but has accepted U.S. military aid. President Bush has agreed to meet within 90 days with Mr. Barco, President Alan Garcia of Peru and President Jaime Paz Zamora of Bolivia to discuss the drug problem. It might not be a bad idea to do that sooner, rather than later. After the Panama fiasco, they will need some reassurance. Certainly, the Colombian press is much in need of that. <sep>In the response to the Panama fiasco, who has President Bush agreed to meet with within 90 days to offer some reassurance?<sep>Jose Abello Silva
