There is no single country that has violated national sovereignty MORE than the USA in the last 100 years. NONE. (Just to be clear, I have no confidence whatsoever in the claim that the Russians interfered with the 2016 presidential election. None.)
US have subverted elections. (Post WW2 Italy springs to mind, but also almost every Central and South American country, and SE Asian country too. )
And they have bragged about it too.
US have bankrupted small nations by bribing their elected officials into approving public works projects they did not need and could not afford. And they did it just so they could better control them.
US have armed and trained warlords, drug lords, and terrorists to sow chaos and destruction in regimes/governments they do not like.
They have assassinated and overthrown dozens of popular, and often democratically elected foreign heads of state for the most thinly disguised reasons and kept it secret from the world and the American people.
The list goes and am afraid I can’t continue as I have better this to do.
