Let us try a thought experiment.
Imagine that Hamas has a legitimite gripe with an Israeli general - say, someone they claim is responsible for killing civilians in Gaza - and wish to kill him. On hearing that he is visiting the US, they arrange a bombing. This bombing - which may or may not kill the general - kills 49 American civilians. Images of mangled corpses of women and children fill TV screens.
The response would be obvious. Regardless of whether you supported the right of Palestinians to struggle against Israel or not, such a bombing would be universally condemned. It would be taken as a sign that Hamas was beyond the pale, and needed to be exterminated. Even if it was the other way round, with Israel attempting to assassinate a Hamas leader, it would be universally condemned. No-one has the right to blow up scores of American civilians as part of an assassination attempt, right?
The US just murdered 49 Yemeni civilians - including women and children - trying to kill a Al Qaeda leader.
Now, I was thinking - "would they ever send cruise missiles into NZ?" Would places like Aotearoa, Australia, or Canada ever find 50 civilians murdered in an explosion as the US attempted to kill its enemies?
The answer is, of course, no. For some reason, predominately white, English speaking people would never have to fear the same violence the US feels entirely justified in visiting on Arab countries. I wonder why...?
