Catching the Thief of Baghdad

Nostradamus' Century 10, Q 72

L'an mil neuf cens nonante neuf sept mois,
Du ciel viendra vn grand Roy d'effrayeur:
le grand Roy d'Angolmois,
Auant apres Mars regner par bon-heur.

Translation

In the year 1999 and seven months
The Great King of Terror will come from the sky,
He will bring back to life the great king of the Mongols.
Before and after the God of war reigns happily.

Historic References

In 1257, Hulagu (1217?-1265), the grandson of Mongol conqueror Genghis Khan and brother of Kublai Khan and Mangu Khan besieged and sacked Baghdād after the Abbasid Caliph al-Mustasim rejected Hulagu's demand for Abbasid surrender. In the massacre, only Christian lives were spared, apparently due to the intervention of Hulagu's Christian wife. Baghdād burned for seven days, and some historians estimate as many as 800,000 people, including the caliph and his family, were killed. In a letter to King Louis IX of France, Hulagu estimated his army killed 200,000 people.

The city suffered minor damage from bombing during the Persian Gulf War in 1991, which lingered on as a naval and aerial siege of Iraq by the US-UK military alliance. In mid-April 2003, U.S. forces captured Baghdād after extensive aerial bombardment that destroyed most of the City's commercial and governmental buildings and overthrew the regime of Saddam Hussein. Television crews of the enemy countries were present and active in Baghdad during the invasion and the destruction of the city was shown live on television worldwide as a sort of entertainment. Looters ransacked many shops, warehouses, and museums.

Interpretation

In July, 1999 someone flew to somewhere and formed an alliance to attack Iraq and destroy Baghdad once again as the Mongol king had done in the past. This would be a continuation of the war that was started earlier and was paused, and would continue for an indefinite period.
