The Beginning of World War III

[I.63] Pestilences extinguished, the world becomes smaller, for a long time the lands will be inhabited peacefully. People will travel safely through the sky, land and seas : then wars will start up again

This quatrain is considered to be the quatrain which indicate the start of WW-III. The scenario described in this quatrain is definitely a modern world scenario as is describes air travel. Air travel became commercially available only after WW-II. World is a small place now with ease of communications. Antibiotics helped man to get rid of many incurable diseases. But, Nostradamus says, wars will start up again. Alternatively, this might describe a period of unparalleled peace predicted after WW-III when the Great Monarch will reign, till the "End of the World".
