China sure as hell wont take them.

Nobody will want to take them, but there is a case to be made that China should be made to take them. After all, China is right there and technically a refugee must stop in the nearest safe country, and all evidence points to China being the source of the virus in the first place. However, this would require the liberal white ruling class to a) not take in huddled masses and b) stand up to China. Needless to say their track records on both counts are terrible.

In which case, what should Whites do?

Step one is to learn from last year and ban all travel to your country from India, excepting of course citizens who have the right of return. Those people should be immediately quarantined upon entry. Step two is to develop a test for the new variant - we all benefitted enormously from having a test (developed by Germans iirc) early on in round 1. Step three is to send whatever aid to India.

Right now, Canada, America and Europe have announced millions in aid to support India right now, but you do think this is actually enough to stop the nation collapsing?

Depends on how many millions. $10 million vs 1.3 billion people is not that much. Also, iirc much of India's population lived at subsistence levels before so it may not take all that much to keep them afloat at that standard of living.

Or do you support no aid going to India and instead, fortify Europe against another migrant invasion?

These are not mutually exclusive. Nobody benefits from India collapsing, and the "fortification" is not so much building a wall or hiring border guards as it is deciding that you don't want to become the Camp of the Saints, which costs no money.
