President Clinton today honored the nation's war dead at Memorial Day ceremonies at Arlington National Cemetery. He used part of his speech to focus on his upcoming trip to Europe — he leaves tonight for his first stop: Portugal. Mr Clinton focused on the symbolism of his trip in recognising democratic changes across Europe since the end of the Cold War. He said his visit to Berlin would be the first by an American president to the city since it officially became the capital of a reunified Germany. He hailed Russia's transition to Vladimir Putin's presidency as the first democratic transfer in 1,000 years, and said he would be the first American president to address a democratically elected Russian parliament.
