Protests in Hannover, Germany, as U.S. president Obama visits the Hannover Trade Fair. Protesters oppose the Trans-Atlantic Trade and Investment Treaty promoted by president Obama. A recent Bertelsmann Stiftung research institute poll shows larger rejection of the treaty in Germany than a mid-Feb. poll by German broadcaster ZDF showing about half of Germans opposed. Interviews with a dozen protesters show suspicion about large corporate interests, and fears that the talks are secretive, a sense that the interests of ordinary people would be neglected. Elections in the U.S. in 2016 have shown a surge in sentiment opposing trade agreements.
