One, figure out why you're "anti-Atlantist", and anti-defense pact. Two, think about how radicality created the US problems, and why you think radicalism is the answer in your case.
Yes, Europe needs to change its stance, but electing a "burn-it-to-the-ground" faction is not actually going to do this in a productive way.
As for the "omnipresence" of the US, that is and has always been a lot of individual choices more than a political choice. By all means, fixate less on the US yourself, but I promise you that trying to force that on others by electing a more authoritarian party will backfire spectacularly.
Soft power isn't countered by hard power. The two working counters are increased soft power on your own (i.e. a culture that's more attractive than US culture), or said soft-power self-reducing. You can trust DJT to achieve the latter.
You don't have to "cut ties". You have to learn to think on your own.
I've moved, in 6 month, from a pretty pro-OTAN, "liberal" point of view toward an anti-OTAN, anti-Atlantist position, and i think i'm right. I now would even vote for an anti-atlantist right wing party rather than for the left of center, pro-US party i've voted for before (well, since an anti-Atlantist left wing party exist, and despite its radicality, i will probably vote for them, but i'm now a single-issue voter, and my issue is how omnipresent the US is in our culture).
DJT made me realized i'm part of the problem, and now i can take steps to fix it.
