Buy European

I don't think you're stupid. It's a valid question.

So, tariffs will only affect the US domestic price of things. Importing stuff from overseas to the US will bump the price by the tariff amount. The goal of this is to stimulate Americans to buy American products. Or rather, deter them from buying something not American.

The Buy From EU movement is essentially the same thing, but rather than doing a deterrent, we will try to encourage Europeans to use European (or just non-US) products or services.

So no, Microsoft will not become more expensive outside the US, they will most likely not pull their services from the EU as they need us just as much as we need them.

The goal of this is to show Trump we don't really care about him wanting the US to end up in economic isolation, whilst at the same time bolstering EU economics.

But to the be clear: there are exactly 0 winners in tariff based trade wars. You can reason all you want to find some positive examples, like:

• less overseas shipping (meaning less fossil fuels, less pollution),
• stronger domestic economy (because you can no longer import stuff, you'll have to make it yourself), - or maybe better products (because you'll still have to compete with overseas products).

But:

• because of the splintering you'll have more production facilities and stuff still needs to be moved within the economic region
• because of the splintering, companies will have to sell at a higher price to cover cost of lower capital outlay
• because you'd have to reverse engineer stuff to produce it yourself, you'll make an inferior product at the same, or higher, price.

But mainly: getting the tariffs to work will take a lot of time. It's essentially a reboot of the system we have been building for a century. But the time the tariffs will have the desired effect, consumers will no longer have the money to even spend on these new domestic products.

It will be like the Great Depression which will be followed by a war. History will inspire our future.

That said I can't wait to see 2070, sadly I'll be old and grey by then. If not dead.
