Trump 2 is worse than Trump 1 by far from EU perspective. And it also proved that it wasn't a once-off that Americans will vote in someone who threatens to dismantle NATO, invade Greenland, or start trade wars with allies for no reason.
Also Trump 2 proves without a doubt that at least half of the american voters are absolutely insane or incredibly stupid. For 1 there used to be some doubt.
We in Europe are enjoying roughly 15-20% insane/stupid ratings at this point, which is not great but still a bit better.
From the a US perspective, EU hate each other and I see no way any temporary cohesiveness will last. Most EU countries are just as likely to elect a Trump in the next decade
Let's face it. Trump 2 is about dismantling democracy. The administration radiates hostility and aggression to anything democratic. In the new national security policy the EU is the adversary of the US. If that isn't a wake-up call.
