I'm not sure what your point is? Irrespective of the past (whatever wrongdoing the US may or may not have engaged in), it matters not to the current situation for the people of Crimea, Cuba, Iran, North Korea, and Syria.
Obviously I think the Trump Administration is terrible, but do you really think it is at the level of Iran or North Korea? Please. If it was, I would be willing to die for liberty, absolutely.
The US is not going to lift these restrictions. Why would they? If you live in these terrible places, I’m sorry, but you need to start fighting at home. I don’t know enough about your specific situations or what level of action you should take, but everything from peaceful protest to armed rebellion are options. Yes, you might have to die. You might be killed just for peaceful protest or if you’re government suspects you might be “trouble.” This is your burden, but liberty is worth it.
