Whether a country massacres its own people is not really a good litmus test since there are countries that treat its own citizens well but foreigners really badly. One such country is… oh the US!

How could you think those two, massacring your own people and buying plane tickets home for people illegally here are on the same scale at all. We are not ideal here at all but we don’t do that and I think if it were tried there would be an uprising against whoever was calling that unimaginable shot.

You might be omitting the foreigners that are not in the United States that are being treated rather badly by the United States. I suspect that's what GP was referring to.

How about bombing a school?

This is a really, really messed up opinion.

Who cares if a country installs a panopticon to monitor their citizens and runs them over with tanks, look at this other thing over here.

Yeah that "other thing over here" is totally irrelevant. It's not like it's the actions of the second country in the comparison or anything like that.

Suppose country A kills 1000 people and country B kills 1000000 people and people are criticizing country A for murder while calling country B a better alternative. What is relevant here?

Are you implying China treats foreigners well?

How many schools has it bombed recently?

You sincerely think a country that massacres its own people is better than the relatively good conduct of the US during war (or the treatment of foreigners on its soil)?

Why do we keep on getting into these wars in the first place?

"Good conduct during offensive warfare" is one of those contradictory expressions like "clean coal".
