It is true that both European and American elites both embrace neo pagan, hedonistic decadence. Both control the media, academia, entertainment and critical silicon based industries. In Europe their power is codified within the EU. In America thanks to our Bill of Rights and Constitution, the elites have great power and influence but at least for now as evidenced by the last election, the American people when united around common , decent values are capable of resisting and asserting themselves.
There lies the problems for America’s future. As long as we are a united country as Lincoln said, no foreign power could as much take a drink of water from the Ohio river unless they were invited to do so by the people. If Americans share a consensus of decently held common values, almost irrespective of the readiness of the armed forces, no foreign country could ever hope to conquer us or impose their yoke upon us. Lincoln warned that could only happen if we lacked that unity. Sadly that unifying consensus no longer exists in America. Military spending and foreign entanglements will not make us secure. The stark difference in values that separate contemporary Democrats from Republicans allows no real consensus.
The "Biden" regime showed how easy it was for the Deep State to embed personnel in social media companies to use big corporations to suppress political speech, and when combined with pressure on banks to debank political opponents and the abuse of tax and prosecutorial discretions, shows how close we were getting to a fascist one-party state.
And should the Dems win all three branches again, all of those will immediately be back on the table, along with court packing, which would inevitably give us European-style suppression of free speech.
The whole point of a Constitution is to prevent that from happening at all: so this means the Constitution really isn't working-- it's on life support.
Staying involved in Europe and turning its politics around back to what they once were would help a lot to deligitimize similar attempts here.
And while I agree the "crisis of a house divided" is by far the biggest problem the US faces, that doesn't mean that external enemies are somehow respecting a timeout while we fight internal battles.
