That's the main tool in the empire apologist's toolbox these days: arguing with reality. If you point out the reality of where people are at in Moscow and Beijing with regard to western provocations on their nations' borders, their only answer is to say "Yeah well that's not how things should be so we're going to keep doing what we're doing." 

It's like being warned that you'll get punched if you keep yelling ethnic slurs in public but doing it anyway because you believe people should respect free speech, and then melodramatically clutching your broken nose and yelling that what happened should not have happened. Reality doesn't care about your ideological shoulds and shouldn'ts; as far as reality is concerned, there's just what happens and what does not happen. If you actually want to avoid certain outcomes, you can't just heap a bunch of conceptual shoulds and shouldn't on concrete circumstances - you've got to actually conduct yourself in a way that steers clear of those outcomes.
