美国有线新闻 CNN 美或派一艘驱逐舰进入黑海 纪念珍珠港事件77周年（在线收听）

The first one takes us to the Black Sea, a body of water surrounded by Bulgaria, Georgia, Romania, Turkey and also Ukraine and Russia. Those last two countries have been involved in a conflict in eastern Ukraine since 2014. And tensions between them rose even more after a confrontation between Russian and Ukrainian ships last month near the Kerch Strait.

That's a narrow passage of water that links the Black Sea with the Sea of Azov. Russia captured three Ukrainian ships in the encounter and now an American warship may be headed for the Black Sea. U.S. officials say this would be in response to Russia's maritime actions against Ukraine. The U.S. Navy says it routinely conducts operations in the international waters and airspace of the Black Sea. But earlier this year, a U.S. military official says the Navy was increasing it's presence in the area to counter the increased presence of Russia.

That country's making moves of it's own in the region. In eastern Crimea, a peninsula that Russia controversially annexed from Ukraine in 2014, Russian troops recently conducted a military drill involving anti- aircraft missiles. Their country says that Ukraine is taking steps toward a military offensive so there's a lot of international flexing taking place in this tense part of the world.

PRESIDENT FRANKLIN ROOSEVELT: A date which will live in infamy. The United States of America was suddenly and deliberately attacked by naval and air forces of the Empire of Japan.

CARL AZUZ: On this the 77th Anniversary of the attack, the USS Arizona Memorial is one place where events are held on National Pearl Harbor Remembrance Day. It's an observance that the U.S. Congress established in 1994 and it's when survivors, their families, veterans and the public gather to honor the victims. The assault on Pearl Harbor was at the time the deadliest attack on American soil. It led the U.S. to join China, Great Britain and the Soviet Union, the allied powers, in their fight against Germany, Italy and Japan the axis powers.
