Argentina is 2400 miles long from north to south (the USA is about 2700 miles from the Pacific to the Atlantic) and is four times the size of Texas. The population is 40 million, with Buenos Aires at 3 million. Peru is three times larger than California, with a population of 30 million, but Lima has 9 million people. The flag of the former is blue and white, with the Sun of May, a representation of the Inca Sun God, in the middle, while that of Peru is to the right.
Neither country has yet been hit by a hurricane, and while Peru does have some significant earthquakes, Argentina's major ones are in the west and north. Buenos Aires is a safer city with respect to natural disasters.
The president of Argentina, as earlier reported, is Cristina Kirschner, while Ollanta Humala this year beat Keiko Fujimori (graduated from Boston University) for the Peru presidency. She is the daughter of Alberto Fujimori (an agricultural engineer and mathematician, he was known as El Chino, or Chinaman), former president, who is now in a Peruvian jail. In 1938 he was born in Miraflores, where my Lima hotel is located. If she won, she probably would have pardoned her father.
Education in both countries, incidentally, are compulsory and free, even through college (undergraduate), providing you qualify.
Well, what else? Miss Universe in 1957 was Gladys Rose Zender de Meier (left) of Peru, and in 1962 was Norma Nolan (right) of Argentina.
