Venezuela attack could embolden China and Russia, says Emily Thornberry
Failure to condemn US intervention risks encouraging others to take similar action, warns senior Labour MP
The lack of western condemnation of the US military intervention in Venezuela could embolden China and Russia to take similar action against other countries, a senior Labour MP has warned.
Emily Thornberry, who chairs the Commons foreign affairs committee, said that without a coherent and strong response to Donald Trump’s move at the weekend to remove the Venezuelan president, Nicolás Maduro, and bring him to the US, the norms of international law could break down.

To add to the madness of it all, the attack on Venezuela is clearly, above all, an oil grab. But we scarcely need oil any more.

In the short run, we can survive the decline in wealthy countries by reopening the door to immigrants, which would also offer sanctuary to people fleeing from the climate breakdown and conflict we've caused overseas. Two wins, in other words. In the long run, we'll steadily shuffle away.

Of course, if economic and social life collapsed, the process might go into reverse, and birth rates could be expected to rise again. But is that really what you want?

Because the issue of population change is so widely misunderstood, here's a short thread which seeks to lay it out simply.
It explains why there is almost nothing anyone can do to change the global population trajectory, both as numbers rise, then as they fall.
