All will tell lie.
It wasn't any one country. The whole allied side and others bordering the offending countries (the axis) got to have a say in the punishements.
The country would not be secular.
DEATH!
It would be total anarchy.
hi
destruction of the whole world
We would all be 'not good'.
the whole world would freeze and we would die
If the entire royal family of a country were to die, the government would follow established protocols to determine succession and possibly appoint a new monarch. This could involve tracing lineage, holding elections, or appointing a new ruling body, depending on the country's constitution and laws.
Then we would have only whole numbers. no fractions of any sort.
the country as a whole
The same as would happen in any other country: you could not use any electricity!
