New World Order takes over the world by taking control from the top of key organisations. Buddhism reduces and even eliminate pain of humankind by working from the very bottom of human social class.
The Buddha himself was a prince of the Shakya clan of the Indian subcontinent in the 5th century BCE; until he decided to stop sensual indulgence, attain enlightenment and pass on the teachings he attained.
Buddhism is the final remaining threat of the New World Order. Any human accustomed to concepts of creation and God shall already be corrupted by then. Atheist who lacks proper awareness and mind conditioning are next. Maitreya of Buddhism will only re-emerge at a time when Buddhism is no longer practiced.
The coming of Maitreya will be characterized by a number of physical events. The oceans are predicted to decrease in size, allowing Maitreya to traverse them freely. Maitreya will then reintroduce true dharma to the world.
The scriptures say that Maitreya will attain bodhi in seven days (which is the minimum period), by virtue of his many lives of preparation for buddhahood similar to those reported in the Jataka tales.
At this time a notable teaching he will start giving is that of the ten non-virtuous deeds (killing, stealing, sexual misconduct, lying, divisive speech, abusive speech, idle speech, covetousness, harmful intent and wrong views) and the ten virtuous deeds (the abandonment of: killing, stealing, sexual misconduct, lying, divisive speech, abusive speech, idle speech, covetousness, harmful intent and wrong views).
p/s: Buddhism has nothing to do with idols or worshiping anything. It is a problem solving mechanism, specifically for solving human problems. It's very existence is in fact a direct counter-measure of evil. Buddhism cannot be destroyed, yet it adapts like water into different forms, capable of evolving the next Buddha Maitreya.
