premise: Tens of thousands of Colombians and Venezuelans attended a free concert Sunday, held on a bridge linking the two countries. It was organized by Grammy-winning rock artist Juanes to celebrate the end of the diplomatic crisis between Colombia, Venezuela, and Ecuador, and to further improve peaceful relations within the region. The "Peace Without Borders" concert was staged atop the Simón Bolívar bridge, which connects the Colombian town of Cúcuta with the Venezuelan town of San Antonio del Táchira. "It would have been much more practical and simple to do it in a city," Juanes told the Miami Herald, "but the border is a symbol of peace between all countries. And this message is for everyone, all the countries in Latin America and the U.S. as well."
hypothesis: Ecuador is now allies with Colombia and Venezuela.
