WORLDCRUNCH-TO-GO

The subject of the constitution is all the rage in Japan nowadays, as Prime Minister Shinzo Abe continues his efforts to rid the document of its pacifist provisions. And Japanese women are challenging his three-year-old government with "constitution cafes" and street protests, Philippe Pons writes for Le Monde. "The meetings in Maioka form part of a growing trend of initiatives launched by Japanese women since Abe came to power three years ago," he writes. "Across the country, women are meeting in cafes and restaurants to learn about the constitution and debate the politics surrounding its revision. ‘This movement of political consciousness was born after the Fukushima nuclear disaster in 2011,' says attorney Keiko Ota. ‘Like me, many mothers worried about the health of their children, and we slowly realized all the lies the government was telling us. Revising the constitution to allow Japan to become a full-fledged military power is another issue that worries mothers. This is why they try to understand what's going on. They're asking why Shinzo Abe blindly follows the Americans and wonder if military service will become mandatory.'"

Ahtisaari, a Nobel Peace Prize laureate who was involved in back-channel discussions, said the Western countries were convinced that the Syrian dictator was about to fall and ignored the deal.
