He was stating killing other countries' civilians.
Yes, killing other countries civilians does more to anger them than killing your owns.
Not that the US hasn't recently invented a process of killing it's own citizens without a court order. Not that the Obama administration wouldn't defend it's right to kill US citizens far away from an active battlefield without asking a court.
Till know you are however right that the US government hasn't killed that many US citizens.
As a sidenote that's one of the reasons we need real resistance against the US government. Twenty years ago the US government didn't claim it had the right to kill it's own citizens far away from an active battlefield.
The US political system is deteriorating and it has stopped to be about the rule of law as high level politicians proclaim that courts aren't allowed to review their actions and whether those actions are in accordance with the law.
I read somewhere that Saddam Hussein killed more of his own civilians while he was dictator of Iraq than the number of civilians killed during the US invasion of Iraq.
Those claims often come from comparing apples to oranges. They take the amount of killings during the US invasion that are documented by newspapers and compare them with estimates of killings by Saddam which were made by taking into account that not every death produces a newspaper article.
That's especially in a country where the US supported government targets journalists and thereby prevents them from leaving their hotels and during detailed research on death counts.
There's a study published in Lancet that suggests that the real death count is around ten times the count that gets published in newspapers.
Replacing one government that tortures it's own people and runs death squads by another with tortures it's own people and runs death squads isn't much progress.
In this case the people who are doing the torturing are often even the same that did it under Saddam.
