It worked for iraq, afghanistan, vietnam, etc so it must work for ukraine.
> By my count Japan invaded at least 16 countries during WW2
None of those 16 nuked japan though. You are not as clever as you think you are.
> and occupied a large number of them.
All of those 'countries' were occupied by european colonizers before japan kicked them out. So using your logic, britain, netherlands, france, etc should all have been nuked.
> They were also bombing a number of areas pre invasion such as America and Australia.
Well both america and australia had declared war on japan. Also, america and australia were colonizing powers in asia far worse than japan. You might want to brush up on your history.
But regardless, none of that justify nuking a bunch of civilians does it...
