A plane crash in Western Russian killed Polish President Lech Kaczynski and the other 96 political and military officials on board on April 10. The accident has led to huge national mourning in Poland. But it may provide an opportunity for reconciliation (和解) between Poland and Russia, countries that have a troubled relationship.
Many from the political elite were lost in the crash. Beside the president, the dead include the army chief of Staff, the head of National Security Bureau, the national bank president, the deputy foreign minister and other members of parliament.
The Polish delegation was heading to Russia to mark the 70 th anniversary of the Katyn Massacre (屠杀) when the accident occurred. In 1940, about 22,000 Polish soldiers, intellectuals, and officials captured after the Soviet Army invaded Poland in 1939, were killed secretly by Soviet police in the forest of Russia’s Katyn.
The Katyn Massacre had been a sensitive topic between the countries. The former Soviet Union always denied responsibility for the massacre. It was not until 1992 that Russian released archived documents about the killing.
Katyn is merely a short chapter in Poland and Russia’s long and troubled history. In the 18 th century, along with Prussia, (then an important part of Germany) and Austria. Russia participated in three carve – ups of Poland. In 1795, after the third carve – up, the country was erased from the map of Europe. It was in 1918 that Poland regained its independence. But in 1939, at the beginning of the World War II, it was invaded by Germany and the Soviet Union under a secret pact. After the war, Poland became a communist country with close ties to the Soviet Union.
In 1989, Poland switched to capitalism and pursued a pro – West position. The most recent tension between the two countries was in 2008. That year, Poland decided to have a US missile shield (导弹防御系统) on its soil, while neighboring Russia threatened to aim missiles at Poland.
But the plane crash has created a chance for reconciliation, with Russia sharing the sadness of Poland. Russia has declared April 12 a day of mourning for the victims. Flags flew at half – mast in Moscow. And earlier on April 7, Russia Prime Minister Vladimir Putin became the first Russian leader to mark the anniversary of the massacre.
“I think it should improve relations between the two countries, as Russians feel our grief,” said Radek Sikorski, Pland’s foreign minister.
