Tanks, missiles roll through Red Square on Victory Day

Victory Day, marking the defeat of Nazi Germany, is Russia's most important secular holiday, both honoring the enormous sacrifices of World War II, in which nearly 9 million Red Army soldiers are estimated to have died, and asserting the country's military strength.

Russia has nearly quadrupled its defense spending in recent years, aiming to resuscitate the military forces that deteriorated in the post-Soviet period.

The display of more than 100 tanks, mobile missile units and armored vehicles was aimed at underlining the military revival -but much of the heavy weaponry shown was only slightly modernized versions of equipment developed decades ago.

Although the display was significantly smaller than in Soviet-era parades, the return of the tradition has raised concerns that Russia harbors aggressive ambitions.

But President Dmitry Medvedev, in a speech opening the parade, said "the true purpose of weapons and military equipment is to give reliable defense of the homeland."

Medvedev, who took office Wednesday, stayed away from controversial statements such as predecessor Vladimir Putin's parade speech last year, which implied parallels between the U.S. and the Adolf Hitler's Third Reich.

But he said "we must not allow contempt for the norms of international law."

Russia has consistently criticized both the U.S.-led war in Iraq and wide Western recognition of Kosovo's independence as arrogant violations of international principles.

Putin, who was named Russian prime minister on Thursday, stood just behind Medvedev's shoulder and his face was prominently shown in TV broadcasts as the president spoke -underlining the wide belief that Putin will be the power behind the presidency.
