Why was US peace president killed?

The United States (US) government, not only engages in regime changes all over the world when nations attempt to exercise their own sovereignty, but it has even removed its own government too. President Kennedy was a victim of that! Please click on this link for more: https://youtu.be/TnIe24xMGkg

US Major General Smedley Butler, who in 1935 wrote a book named WAR IS A RACKET, alerted the US Congress of a plot by oligarchs to coup President Franklyn D. Roosevelt. Congress did nothing about it.

The US is a dictatorship with democratic characteristics. That is why the world considers the US as the biggest threat to peace. What else could it be, when the US unconditionally supports Israel’s genocide against Palestinians in their own homeland? When the US has never complied with the United Nations’ (UN) Charter? When the US has maintained an illegal blockade against Cuba for more than 60 years? When the US has repeatedly vetoed UN’s Security Council resolutions for a ceasefire in Gaza? When the US says it supports Taiwan’s inalienable right to self-determination and independence, while it has consistently refused to comply with 42 UN resolutions demanding that it immediately return Puerto Rico’s sovereignty to the Puerto Ricans? And, when 38 million Americans live in poverty, while 9 of the 10 richest men in the world are US citizens?

The UN is in a war venue.
