Especially now that the U.S. government is also talking about not living up to its NATO obligations.
This is not gonna hurt the rest of the world. Defense is where the U.S. exports a lot. So cutting back on U.S. weaponry will only help other nations.
The same is true of Tech. Currently the tech industry is global, but expect it to become increasingly national. Considering this is one of the biggest and fastest growing industries in the U.S. and one of its biggest exports, again, this is only gonna hurt thenUS economy.
And the US’s dominance in this space is so high the rest of the world will simply push for open source at no loss to their own economies, since it’s only the US’s profit making will be hurt.
