This sentiment is a major part of the MAGA platform - just swap “European” for “American.”
Why become isolationist? It’s a weak position. What about countries like Canada, Japan, India, Mexico, etc? Just because the US sucks right now doesn’t mean the rest of the world shouldn’t work together.
“Security” connotes more than military defense. It’s often a concern of economy, which is secured through trade and partnership and international alliance.
But tell me specifically the difference between becoming more independent vs isolationist. Are you simply advocating for stronger European militaries? Ironically, MAGA has also been asking for that - they want Europe to spend more on their militaries.
My position is that the stronger and more prolific the alliances are among nations of the world, the less each individual country will need to spend on militarization (a complete waste of resources). That’s not suggesting that Europe shouldn’t be spending more on their militaries in light of recent events. That’s just an unfortunate consequence of a shitty disposition of US isolationism.
Independence rhetoric does closely align with the rise of right wing nationalism we see throughout the world. I’m curious how you distance yourself from that movement.
