Input: Consider Input: 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>As the struggle against the drug lords in Colombia continues, who was arrested with 1,000 pounds of dynamite?<sep>Leonidas Vargas

Output: Yes

Input: Consider Input: The Dutch Take Over: Intent on capturing a piece of the Portuguese trade in pepper and other spices, the Java-based Dutch Ailied with the Malays in 1633 to blockade Melaka. The trade blockade was to last eight years, and ended in a seven-month siege. The Portuguese surrendered in 1641, wracked by malaria and dysentery and denied their usual reinforcements from Goa. By then, the city had become a stagnant backwater. Unlike the Portuguese, the Dutch decided to do business with the Malays of Johor, who controlled the southern half of the peninsula together with Singapore and the neighboring Riau islands. A trade treaty gave the Dutch command of the spice trade but reserved Johor's rights in tin exports from Perak, Selangor, and Klang. Without ever retrieving the supremacy of the old Melaka sultanate, Johor had become the strongest Asian power in the region. For the Dutch, Johor provided a buffer against other Europeans. Meanwhile, fresh blood came in with the migration into the southern interior of hardy Minangkabau farmers from Sumatra, while tough Bugis warriors from the east Indonesian Celebes (Sulawesi) roved the length and breadth of the peninsula. The Minangkabau custom of freely electing their leaders provided the model for rulership elections in modern federal Malaysia. Their confederation of States became today's Negeri Sembilan ("Nine States"), with Seremban as its capital. The name Minangkabau itself means roughly "buffalo horns" and is reflected in the distinctive upward curving roof in museums and government offices built in the traditional Minangkabau style. The Bugis were energetic merchants and great sailors. With the Dutch concentrating once more on Java and the Moluccas in the 18th century, the Bugis took advantage of the vacuum by raiding Perak and Kedah, imposing their chieftains in Selangor and becoming the power behind the throne in Johor. The Bugis in Johor's administration provided much of the spirit in that State's independent stand in the 19th and 20th centuries. Throughout this period, the east coast states enjoyed a relatively tranquil prosperity, Terengganu notably thriving from its textile industry and trading in pepper and gold with the Thais, Cambodians, and Chinese. The British, under the private auspices of the East India Company (EIC), were beginning to poke their noses into North Borneo. <sep>Who's confederation of States became today's Negeri Sembilan?<sep>Malays of Johor
