Sure, let’s all go back to 1914.

Sorry, Israel, Syria, Lebanon, and Iraq — you were all part of the Ottoman Empire:

Hungary, the Czech Republic, Slovakia, and most of Yugoslavia and Romania were ruled by Austria:

China would need to surrender Manchuria to Japan, and Russia would need to give back most of Sakhalin Island and the Kuril Islands to Japan:

India, Pakistan, Canada, Bangladesh, Australia. South Africa, Nigeria, Egypt, Sudan, and many other countries would need to surrender their independence as the British Empire would be restored:

and so on…

Sounds like a grand idea. Why not?
