Democrats were never the lesser evil, I'm also not American but it doesn't even take more than a simple look to understand this
Bush 1 Iraq war
Clinton Yugoslavia
Bush 2 Iraq-Afghanistan
Obama- More Afghanistan, drone campaign, Syria etc
Trump - Syria, almost Iran, China
Biden - Russia, Palestine
If you want to add Bernie - anti-Cuban statements, pro-Israel statements, pro-Ukraine statements etc. Fucking loser is just another FP ghoul too.
Meanwhile economically and socially the US continues to deteriorate since the beginning of the current neoliberal era(late 80s-90s) as you noticed and maybe Bernie gets a honorable mention for being just a bump on the steep downhill road, nothing more.
Heck we noticed and commented some time now since the beginning of the Ukraine war that current FP is in some ways even more deranged than even what Kissinger would do. Indeed some would even say current policy makes Kissinger look competent in comparison. That's how bad it is. And to be honest some argument does mention that Kissinger was from an era where the US actualy somewhat respected their peer adversaries, these days its all end of history BS.
