And how did the US "ruin" things for the people in east Ukraine? Did the US somehow force the Russians to invade Ukraine?
There was a democratically elected government in the Ukraine.
You (and me) might not have liked that government. But they were the government elected by the majority of Ukrainians.
A violent revolution, encouraged (if not partially planned) by the West, overthrew that elected government.
The people who voted for that overthrown government did not accept the violent putsch/coup d'etat. Especially not because the new rulers declared immediately that they would cut all ties with Russia. E.g. they stated in the first weeks that they would forbid Russian as the official second language of the Ukraine. (I believe a third of Ukrainians speaks Russian as their first language). Stuff like that rubs people the wrong way. No surpise things went wrong. The fact that the new government in the Ukraine decided to take up arms against their own civilians is a strong indicators that the new government is just as bad, or worse, as the previous one. Corruption has certainly not improved.
If the US (and the EU) had not mingled in the internal affairs of another country, Ukraine would have been a lot better off than it is now.
Just like the situation in Syria. Syria was not a fun country. Nobody needs to be explained that Assad is a dick. However, people in Syria could live in relative peace. Different religions were tolerated.
And then Saudi-Arabia and Qatar decided that Assad had to go. And they funded (money and weapons) a bunch of terrorist to start a civil war in Syria. They funded any sunni group they could find. And you can be sure: not much is going on in the Middle-East without the US knowing about it, and condoning it. Result: civil war in Syria, country destroyed, half a million people dead.
Of course the media in the US are not gonna report the story like this. Neither do the media in Europe. Most newspapers and tv-stations follow the official story given to them by their governments. We are the good guys. We came to bring peace. But the "bad guys" don't like our freedom and democracy. Yeah, right.
