Yes, I'm fully aware of that. However, the tech is in island. If the USA goes down, the people who are working at that tech is still in Ireland. The computers are in Ireland.

Same thing goes for goods made in China. If China goes down, America doesn't have the goods, because the goods are not on American land.
