So far, however, this is not as bad as when West Pakistan decided to get even with East Pakistan. Several million refugees poured into West Bengal in India.
It's possible that the population relocations between India and Pakistan upon British withdrawal from the region were even worse. Someone who keeps up on the statistics regarding man's inhumanity to man might let us know.
Then, of course, there was WWII and the tens of millions of refugees created in Eastern Europe and Russia!
We might even toss in the arrival of the Belgians in Congo in the last century ~ now that was bad ~ real bad ~ and there weren't even witnesses!
Whoops, almost forgot a couple of others. Joe Stalin and the Ukrainians, and Mao Tse Tung and the Chinese. Yes, those are still #s 1 and 2 ~ but nobody on the left cares so probably they didn't happen.
You forgot Cambodia and the purge after VN. I was so astounded when it happened, few people seemed to care.
As a Marine stationed in Okinawa, and I can tell you humanitarian aid is already underway. It's still in the process of getting fully underway but it's happening.
