Ukraine means nothing to us generally.
I'm sure half of the US means nothing to you generally.
The problem here is that you need to consider the future of the world.
Do you want a US that is subjugated by Russia and China? Or do you want a US that has some relevance in this world.
Here's some facts.
1) The US's population is 330 million. That's 1/4 the size of China.
2) The EU's population is about 446 million.
3) The EU + US's population together is 776 million, about half the size of China.
4) The UK has 65 million, Japan has 124 million, South Korea has 51 million, Australia has 25 million and New Zealand has 5 million. That's an extra 270 million.
5) All of the US's allies have a combined population of about 1 billion. This is LOWER than China's population. Not including Russia, Russia's allies, and any potential allies that China would get. In fact it's the population of the EU LOWER than China's.
How do you see the world when China is doing what the US did from 1990 onwards, going to war without anyone being able to do anything about it, putting sanctions against anyone it doesn't like and everyone scurrying around to what they tell them to do for fear.
Can you imagine the US being a ***** of China's? Because with your attitude, you better be dreaming it already.
