1. Yes, we are quite literally defending you while doing those things right now.
2. Trump has bad policies yes, although I hadn’t heard anything about an actual military takeover of Greenland.
3. It’s not as if EU doesn’t have tariffs on the Us already, for instance you all are very protective of the auto industry as well as your domestic farmers, just to name a few. I think tariffs are bad policy on both sides of the atlantic
Also even if you sent 100% of the money collected through tariffs back to the EU through Ukraine, what's the point we're back to square one with extra steps in the middle... The US are serving their own interests, it's totally fine, you don't have to pretend they're sacrificing themselves for the greater good of humanity.
Also, the literal advertisement tagline for Apple, one of the wealthiest company in the world, is about how their product "preserve privacy"... so I doubt that privacy is wealth-destroying
