Zionism is a racist colonial ideology, merely using religion as a tool. Theodor Herzl, founder of zionism, said so himself
“We should there form a portion of a rampart of Europe against Asia, an outpost of civilization as opposed to barbarism. We should as a neutral State remain in contact with all Europe, which would have to guarantee our existence.” Source [II]
The comment said "I condemn Hamas" aka the group fighting back against an occupying force and an ongoing genocide. Also said some shitty things about Gaddafi.
It's because of China's sheer size. US sanctions on the DPRK, and — in the past — those on Vietnam and Zimbabwe have successfully kept those countries impoverished since they're much smaller.
It's the threat of a good example right at the US's borders. Even with the embargo, Cuba has free healthcare, housing, better LGBT rights, higher life expectancy, and a proper democracy unlike the US. A thriving Cuba might threaten the US capitalist class and force them to make concessions to the working-class, like the Scandanavian countries' capitalist states had to for being near the USSR (though those have started being undone with the example overthrown).
And it's not just sanctions, the embargo also prevents companies of other countries from trading with Cuba if they also do so with the US. Which the vast majority of them obviously have to if they want to survive competition.
There’s a lot of whitewashing of US history, especially in textbooks. If you ask the average American they wouldn’t even call anything the US did “genocide.”
That's what I mean. The US is built on genocide and colonization just like "israel", but they try to not be open about it.
