Sure, they can do that, but it\'s bad for them.
When you stop exporting, maybe the countries you export to stop getting the benefits from your products, but you stop getting the benefits of their money.
Also, once the US will close outgoing \\ incoming trade, the world will find out it don\'t really need the US in probebly less than a year.
E.g. the oil-rich countries of the Middle East used to export oil to the west in tankers through the Suez Canal. After a few years, the Suez Canal was closed to wide and deepen it so bigger tankers could pass.
Did the oil-rich countries crumbled to dust without the oil trade because of that? No! They built oil pipes that go from them to some place in the Mediterranean, and tankers stock themselves there instead of in the countries\' docks. It\'s alot cheaper to transfer the oil this way because it\'s faster and they don\'t get taxed in Suez.
So both sellers and buyers of oil earned from Suez\' short closing, and Egypt lost, because oil don\'t go through there (atleast not as before).
The same will probebly happen if the US closes it\'s gates. Sure, the US got some good stuff, but when the world will stop getting them, it\'ll only be a motivation to make even better stuff in other places

Edit: The US got
Alaska and Texas and maybe a few places with oil, but they stockpile it incase they get cut off of the Middle East oil supply from any reason (like when the Middle East will be dry of oil).
