Nostradmus has really vague prophecies. Let me show you:
"In the City of God there will be a great thunder,
Two brothers torn apart by Chaos, while the fortress endures, the great leader will succumb",
The third big war will begin when the big city is burning"
What can all this mean? Some people believe this predicted 9/11.
The City of God could be Jerusalem, Rome, any place with a church, could be a million places. A great thumder can also be a million things. A bomb, a building collapse, a fire, a gunfight, train crash, anything. The two brothers? Think of two nations! oh Israel and Palestine. Pakistan and India? Fortress? well, there are about a million different fortresses on this planet. A third world war because of a city burning? No duh! If someone attacks and leaves a city burning there's a good chance of war.
See? I'm sure you can use that to explain other historical events.
