Poland’s freedom icon Lech Walesa yesterday said the United States was “no longer the main global power” in political and moral leadership ahead of a visit by President Donald Trump. Trump is due in Poland on Sunday for ceremonies marking 80 years since the outbreak of World War II. “President Trump, I urge you to regain the position of world leader for the USA,” Walesa said in an interview published in Thursday’s edition of Poland’s centrist Rzeczpospolita daily. “The world needs the leadership of the USA. Moral and political leadership, not only economic and military leadership,” added Walesa, a Nobel Peace laureate. Walesa led the Solidarity labour movement that brought a peaceful end to communism in Poland in 1989 and became its first post-war democratically elected president in 1990.
