A week and no-one has replied? This is what happens when I start threads, too
I'll comment on yours first:
1. His "exoneration" was inevitable once the impeachment was formalised. This is indeed big news, despite being entirely expected, due to its implications for western democracy.
2. Trump re-election would not be big news. Sanders winning would be huge, globally, a first successful fight back by the left against the populist demagogues who are shouldering their way to power across the world.
3. Meh. It could go on for decades. I think public interest will reduce to tedium quite quickly.
4. Could happen. US/Russia proxy wars are kind of old hat. It would be more of a shock to see China get involved.
Four of my own below. I'l continue the numbering to avoid confusion
5 - SEC approves a bitcoin ETF. There's got to be a genuine chance of this happening, after they
approved the Stone Ridge futures fund a couple of months back.
6 - Iran starts and slowly ramps up attacks against US (and allies') interests. I think this would have started already, were it not for the incident with the missiles and the Ukrainian plane, which has led Iran to lie low for a while. But it would be a mistake to think they'll forget or just go away. They won't.
7 - The world's first war over water. A taste of things to come as climate change takes hold and fresh water becomes a hugely valuable commodity. Tensions have been brewing for years about the
Ethiopian dam on the Nile, and its effects on the countries downstream, notably Egypt. We are familiar with conflict over oil; in the future it will be water. Ever wondered why China is so protective of the Tibetan plateau? It's the world's largest non-polar repository of freshwater, and the source of the major rivers. Future conflict with a thirsty India to the south has to be a concern.
8 - Vegetarianism disappears. ... because veganism is becoming huge. For decades, being vegetarian was a big thing, whilst vegans were the weird extremists. Now veganism is pushing towards the mainstream, and vegetarianism is becoming little more than a meaningless half-way point on the road. It's a parallel to modern politics, where extreme right and extreme left own the stage and moderates are no longer relevant.
