Odd that you would say the US can survive without the other nations. They clearly require major inputs from other countries just to exist but those in the US have been told for so long that they do not they actually believe it.
But then again the US could exist at about a 1900's level but not as a modern society.
I think you misunderstood my statements.
The goal is to be ss self sufficient as possible. As it is now we do need imports. But there is not a single nation that the US is dependent upon.
There are materials, like tin, that the US imports because we do not have a high concentration (it would be very much cost prohibitive to rely on US tin).
Then there are elements like cobalt which Canada exports but is not mined significantly in the US because we can import it cheaper (and environmental concerns over mining).
My point is that the US could relatively easily survive without Canada, not that the US would maintain its economy without replacing Canadian imports should the relationship be severed all together. If the US stopped imports from Canada today then we would have to rely more on Asian nations.
Here is our reliance (main points):
1. Canada is our biggest supplier of imported crude oil. 64% of the oil we use is produced domestically while the rest is imported (with Canada supplying about 60% of imported oil). The US can meet 100% of its natural gas needs domestically.
2. The US is the largest investor in Canada.
3. Canada depends on the US for 74% of its exported trade. Canada is one of the largest importers of US products (the US depends on Canada for 16% of its exported trade).
4. Militarily Canada cannot defend itself against major conventional invasion but relies on the US military. Canada has a history of under funding its military while relying on the US to provide protection.
WHY BRING THIS UP?
1. The US and Canada are tied at the hip. Both benefit from the relationship. But the US is not dependent on Canada in the same sence that Canada is dependent on the US.
2. The "complaint" is that the relationship between the US and Canada has been a bit lopsided.
It has never legitimately been an issue of cutting off Canada, but rather establishing a more fair trade based on contribution rather than economic need.
