Beginning of the third and last world war.

first europe and japan go bankrupt. Then soon after, the USA.
in most countries unemployment reaches 60 %.

China then got nobody to buy their plastic crap anymore and goes bankrupt, too. They decided to finally invade taiwan and other parts of asia in an carefuly planned assault. They might start a war with india. Thay ally with russia and pakistan. They slowly replace russians who dont reproduce anymore too. time to use all that military stuff projects they copied from russia and occidentals for decades. Not the best stuff in the world but their amount of soldiers willing to die outnumbers any army in the world. You kill one, ten more are coming.

The USA have the best, biggest army in the world but cant do shit and project it oversea anymore as their homeland is collapsing morally, economically, socially from the inside.
In the middle east iran and strenghetend islamist allies finally attack israel at the same time china invade his neighbors with its huge army. They have no troubles convincing the billion of hungry illiterate chinese that it's their finest hour to invade the world and rule it. The usa cant deploy its army in both afghanistan, china, taiwan, india, israel , korea...and europeans have no armies anymore anyway. half of their soldiers are of muslim confession already.
North korea with the help of china nuke south korea.

Whole eurasia and africa become a sino muslim block. Caucasians disapear from europe.

Europeans are slowly replaced by muslims while chinese replace everyone in asia just like they replaced tibetans.

It will all start with the economic collapse first. All christians and jews worldwide must reunite in north america to prepare the realm of God on earth, after the final conflict.
