I'll quote another comment of mine in this same thread.
The majority of people who fell into this camp of refusing to vote for her were Palestinians. They had every right not to vote for someone who openly said she would continue to fund and arm the people killing their families and utterly destroying their communities. The correct thing was always for the Democrats to support human rights globally, to stand firmly against colonialism and stand with the Palestinians. They refused to do that. It’s honestly incredibly gross to find fault with people refusing to politically support people who are explicitly involved in the destruction of their people.
The continuing refusal of liberals to have any empathy for Palestinians is entirely emblematic of the failures of the democratic party. Over and over and over again you will compromise on genocide, compromise on human rights itself, to defend the disgusting political decisions of the democratic establishment. It's never the fault of the democratic establishment for funding and arming a genocide, it's always the fault of the minorities who wouldn't vote for a party support the killing of their families and razing of their communities. How in god's name do you plan to fight against fascism if you can't even stand against racist colonialist ideology in the political party you support?
I don't think this is currently possible under the current treaties of the EU. At the very least, there is contention about whether it would be possible. It's also not really an overnight kind of situation. At the very least, closer ties with the EU are definitely good for the country.
