It should be pointed out by people first. I'm from Argentina but I was in US earlier this year. Someone was complaining about how the Russians influenced the election. I asked if he considered that in the last 50 years USA is well known for interfering in other countries politics. That his complaint was like a bully crying of having been bullied. He told me that it was a good point and didn't considered before. He is an smart and informed person but for some reason didn't saw earlier how his country affects other countries. Just the other way around.
It is only by universally applying principles of law and moral that we can change them, because you never understand why breaching another nation's sovereignty is wrong (even though this is in the UN charter) unless it is done to you.
It's never OK, because of the US past actions it's hypocritical to get overly upset when it happens to the US unless also accompanied by an effort to stop in the future. If the US deserves untampered elections, the rest of the world does too. Even if it means the new government isn't fond of the US
I don't think any of the premise of this thread is that there's no western propaganda. There obviously is.
Political campaigns are also essentially propaganda, as are what's put out by the PR departments of the military, Department of State, White House, think tanks, and even corporations.
I almost never see any of this pointed out, much less questioned in the US media. It's like they're either not even aware of it or don't care.
They freak out over Russian, Chinese, or North Korean propaganda, though.
