How is this even a deal? Ukraine gets basically nothing in return.
This is just extortion.
Myths like this have always made me kinda angry. Anybody that has owned fish for more than a few days could easily say that this isn't true at all.
But aside from that - animals simply wouldn't exist if they were that stupid. The world is a dangerous place, especially underwater. Not having even basic memory and pattern recognition would be a one-way flight to extinction.
Depends on by whom and how long. The US produces a lot of things but also imports a lot of critical goods and materials as well.
If Canada, Mexico, China, and the EU & UK all banded together for sanctions or embargoes? The US economy would be pushing daisies pretty quick. Especially if the actions were coordinated and did not give the US time to react and adjust.
But the countries issuing those actions wouldn't be in good shape either. Trade wars are a 2-way street.
Military service is a hard concept to grasp when you're sitting comfy at home, not a care in the world and all the conflicts are "over there".
It's a very different story when there is an existential threat looming over your head, weighing on your shoulders like a mountain. Canada's armed forces is already meeting its yearly recruitment targets due to repeated threats of invasion from the United States.
America's unstoppable thirst for short-term profit is why they currently have a corporate-backed fascist in office that is threatening to invade US's (supposed) allies to pillage their resources and economies.
Whether they do or not, the US as we have known it is in its death throes. They have surrendered nearly all of their soft power and made themselves a trade pariah. Entire industries are going to crumble as megacorps swoop in like vultures to devour the carcasses as the walls of their economy close in and the whole building collapses. It is in everyone's best interest to move their interests and money as far away from the US as possible.
Elizabeth Holmes comes to mind. She manoeuvred herself into a position of wealth and power by defrauding other rich people and got herself 11 years in prison for it. That's 11 years more than most other rich scumbags get.
