You are blaming the US for that?
Arbenz in Guatemala, Allende in Chile, etc.
Haiti: Historian Hans Schmidt notes that, “US Navy ships visited Haitian ports to ‘protect American lives and property’ in 1857, 1859, 1868, 1869, 1876, 1888, 1889, 1892, 1902, 1903, 1904, 1905, 1906, 1907, 1908, 1909, 1911, 1912, and 1913. Finally, tired of all those round trips, the U.S. occupied Haiti from 1915 to 1934."
Among others, in the 1980s, a Guatemalan military that received U.S. support carried out scorched earth campaigns that massacred upwards of 200,000 mostly indigenous people [1].
And that's before you count all the other American-trained and armed military juntas that systematically murdered, tortured, and raped millions of dissidents "leftists" with Uncle Sam's blessing.
Wikipedia has an entire page on it: go take a look. [2]

Every leftist country will either be undermined secretly (Europe), will have fake elections to overcome this problem (Latin America), or endure another fascist coup.
In Europe this fascist US backed coups happened until the 70ies. Now the press is enough to vilify citizens and workers rights.
Just like in Vietnam, the stated goal was to replace the government - in this case, to remove the Taliban - that's why you created the Afghan National Army and their flimsy democracy. All told, the US has spent $8 trillion and several thousand young men on the GWOT. Once the US pulled out, the Taliban strolled back into Kabul.
$8 trillion will reduce the US debt by 25%, or pay off all student debt, or build 80 million $100k homes. Wasted, and the only thing you have to show for it is nothing tangible, except more vibrant terror groups, and immigrants flooding Europe. Meanwhile, 8k US veterans die by suicide yearly.
You had the firepower but failed to achieve your political goals. Just like in Vietnam, Iran, Syria, Laos, Cambodia, and more countries than I care to mention. While ruining the lives of innocent millions, of course.
So, you failed. Admitting it might be hard, but it will bring the US to a place of humility and help you avoid adventures like this going forward.
And to be pedantic, no you can't raze every sq. km of 652,860 km². Assuming, even just 1000 tons of explosives per km2, that's nearly 700 million tons of explosives. At $30k a ton, you'd be spending $21 trillion on enough explosives.
